Troubleshooting

ROB RUN Stuck Loading or Compiling Shaders?

Check the connection, install pending Steam updates, and verify game files before reporting a persistent freeze to Kefir.

Guide overview

If ROB RUN stays at the loading screen or freezes while preparing shaders, note the exact screen and any error code. That detail helps you choose the next step and gives support something to work with.

Restart the game and Steam

Confirm your internet connection is working. Quit ROB RUN, exit Steam completely, reopen Steam in online mode, and let any pending updates finish before launching from your Library. If other players are reporting the same issue, check the developer’s Steam announcements before retrying. Kefir’s loading guide

Verify the installed files

  1. In the Steam Library, right-click ROB RUN and open Properties.
  2. Choose Installed Files, then Verify integrity of game files.
  3. Let Steam finish checking and downloading files before starting the game again.

If the game still freezes during shader preparation, update your graphics driver through the GPU manufacturer and restart Windows. Kefir’s loading guide

Use the error code to narrow it down

Kefir associates E-0124 with asset loading and recommends file verification. E-0301 and E-0302 indicate an outdated game version. For another code, look it up before changing any settings. Kefir’s error code reference

If the freeze persists, send Kefir your error code or screenshot, PC specs, and the point where loading stopped. Contact Kefir support
