How to Fix ROB RUN Stuck on Compiling Shaders

The biggest Compiling Shaders freeze, on November 7, was a server outage, and PC fixes didn't get players in. If you're stuck, check the servers before you reinstall anything. Then read the text next to the loading bar: each stop has its own fix.

Why is ROB RUN stuck on Compiling Shaders?

On its biggest day, it was the servers, not your PC. The big wave hit during a DDoS attack: a flood of fake traffic that knocks servers offline.

Eleven Steam threads about the freeze opened on November 7, between 05:51 and 22:27 UTC. The developers' post about the attack went up at 10:09 UTC. Players pointed at the EU states, as ROB RUN calls its servers, and many had played the day before.

Local fixes failed that day. Players reinstalled, verified files, wiped the NVIDIA shader cache and tried a VPN, and the bar stayed put. They got in once the servers came back.

The bar at the bottom of the launch screen also tells you where the launch stopped. The text at its right end changes at each stage:

The lit part of the bar runs to 80%, the last stop players get stuck on. The 50% and 80% points come from players' screenshots. Compiling Shaders stalls show up at 0% or around 50%.

Is it your PC or the ROB RUN servers?

If other players are stuck at the same moment, it's the servers. A few quick checks tell you which:

• The official channel posts a restart or an attack: it's the servers. ROB RUN's Telegram channel warns 15 to 25 minutes before planned restarts, in Russian. Steam news, the pinned Steam threads and the official Discord carry the English posts.
• Fresh "stuck on shaders" threads on Steam: it's the servers. Wait instead of reinstalling.
• A friend in your region loads in, you don't: it can still be the servers. On November 7, plenty of players said their friend was playing fine.
• Another Steam account loads on the same PC: that points away from your PC. Only two players report it, so treat it as a hint.
• Shader screen never moves in Russia: that's likely a network block, not the outage. One creator got past it on November 8 with Cloudflare WARP, a free VPN-like app, plus a second network tool. It's a single report.
• Nobody else has the problem for hours: now it's worth working on your PC.

The launch bar also downloads startup data and connects to your region. Both need the servers, so an outage can stop the bar early.

How do you fix Compiling Shaders stuck at 0% or 50%?

Start with the fast checks and stop when the game loads. The early steps are quick, and the file check and cache wipe come last:

Steps 3 to 6 follow the developer's fix list, which also says to check your internet first. The 5-minute wait comes from one player who got in from 50% after that long.

The shader cache wipe is not a confirmed fix for ROB RUN. Players who wiped the NVIDIA shader cache on November 7 stayed stuck. Skip the reinstall too: it didn't help the players who tried it that day.

Game loads but runs slow once you're in? That's a settings problem, and our best settings guide covers it.

Why does it say "Waiting for status information"?

It's the game waiting on the server as you load into a place, likely because of the DDoS attacks. You see it at 80% on launch, or on the way into your plot, Lenny's Motel or Looty Bay. On the way into a place, the game drops you back on the map after about a minute.

Players fix it with a quick restart:

Playing in a party? Everyone restarts, or the group sticks again.

On a different state from your friend? That's a separate problem, and our server switch guide covers it.

Some players see the hang every 25 to 30 minutes. Restarting each time is the main workaround. If the hang keeps coming back, run Verify integrity of game files once: it fixed it for one player.

Which ROB RUN error codes point to the server?

E-0101, E-0110 and E-0201 point to the server connection. These are the official codes you'll meet while loading:

E-0303 is the one code where waiting is part of the official fix. Give it the full 10 to 15 minutes before you verify.

So check the servers before your PC, and leave the reinstall for last.

FAQ

Why does ROB RUN say "Failed to load il2cpp"?

Windows Smart App Control, a Windows 11 filter that blocks unsigned apps, is stopping one of the game's files. Three players on Steam hit it, and turning the feature off fixed it.

You switch it off in the Windows Security app. Recent Windows updates let you turn it back on later without a reset.

Does ROB RUN have Asia or Oceania servers?

No. ROB RUN runs only Europe and North America servers. Asia or Oceania won't come before the end of 2026 at the earliest.

From Asia or Oceania, every load travels to a distant server, so give "connecting to region" extra time.

The region switch sits in Settings > Other > Region and works only in prison. Easier server selection is planned, with no date yet.

How long does Compiling Shaders take in ROB RUN?

There's no official figure. One player got in from 50% after 5 minutes. On November 7, the stall lasted until the servers came back.
