Guide overview

If ROB RUN freezes on Compiling Shaders, fully close the game and Steam, reopen Steam online, and let any pending update finish. If the same screen freezes again, verify the installed files before changing Windows settings.

Restart from the Steam Library

Make a note of the screen, progress percentage, and any error code. Exit ROB RUN and quit Steam completely. Reopen Steam in online mode, check Downloads for a pending update, and launch the game from the Library once it is ready. If the game closes normally, use the regular exit. Use Task Manager to end the game only when it remains unresponsive. The progress percentage by itself does not establish the cause. Community shader troubleshooting walkthrough

Verify files and check your graphics driver

In the Steam Library, right-click ROB RUN and go to Properties → Installed Files → Verify integrity of game files. Wait for the verification and any downloads to finish, then relaunch. If the freeze persists at shader preparation, install the appropriate graphics driver from your GPU manufacturer and reboot. Test one change at a time so you can tell which step helped.

Report a repeatable freeze

If you can still reproduce the freeze, send support a screenshot or exact error code, your Windows and GPU details, and the steps you already tried. If friends on the same server also cannot enter the game, include that observation. Check Kefir’s official channels if several players see the same freeze. Current outage status is pending confirmation. Kefir's ROB RUN Help Center
