VRChat - Unity 2019.4.40f1_a9b0e14ddd73 Crash

Every time I when I’m about to join either my home world or even the default home I get this error, VRChat stops responding then crashes. I’ve uninstalled and reinstalled VRChat, Steam, SteamVR, Unity and nothing fixes it. I even found a “solution” that said to unplug your 2nd monitor which I did but it still crashes. I just bought VRChat+ in January and I really don’t want to think I’ve wasted $100.

I tried asking someone with this error about thier hardware and drivers, like maybe more AMD GPU trouble, and thier response was that thier computer was “a good Windows 10 computer”

As an example I’ve got i5-10400 CPU, 32GB of ram, and a GTX 1080. Although right now I’m on my phone and can’t check GPU driver version. dxdiag or gpuz will say.

This is what I got

A billion different reasons can cause a crash. Check the logs. They should be under “%appdata%..\LocalLow\VRChat\VRChat”. They should contain more information about the issue.

What should we be looking for, afterwards?

Open the latest log and scroll to the bottom. Look for entries that look related to a crash.

I don’t know if it’s safe to upload them, as I don’t know what kind of personal information might be contained.

This is what I found:
The file ‘archive:/CAB-f6a62a871a5b12610f8dc2fd8baac953/CAB-f6a62a871a5b12610f8dc2fd8baac953’ is corrupted! Remove it and launch unity again!
[Position out of bounds!]

Can’t seem to find this file though.

This seems to hint at a corrupt asset bundle. I wonder if the cache isn’t wiped even if you uninstall/reinstall?

Try deleting the Cache-WindowsPlayer folder (under %appdata%..\LocalLow\VRChat\VRChat), uninstalling VRChat, and reinstalling it again.

Done. Same result. Same file. I’m going to try and uninstall all unity and run again with clearing all caches.

Nope. Still crashes with the same error.

Tried that, DDU my GPU drivers and still nothing. I’m afraid I am permanently SOL. Well, gotta to text a lot of friends I’ve made over the past 4+ years.

After looking around the net a bit, this seems like it pops up occasionally for various Unity assets.
Have you tried using (Restart) after uninstalling? Uninstall (VRchat and Unity) → Restart → Install ?

Oh! Also, note where Steam keeps your files before you uninstall. Check that the folder is actually empty after uninstall, and if not you may have to manually wipe the folder contents. (Right Click)->(Manage)->(Browse Local Files)

–On some Windows builds “Shut Down” doesn’t fully clear the cache, but “Restart” does.

Then after reinstalling check if it crashes again. If it does you can try to check the file integrity of the VRChat install. In Steam that is (Right Click game)->(Properties)->(LocalFiles)->(Verify Integrity)

Any further than that and I presume you’d have to ask questions on the Dev forms for Unity to find out where this “archive” folder is.

Thank you. On the recommendation from a friend I’ve used Revo uninstaller to try and find any files associated with VRC and unity but still get the same error. I’ll try the unity devs. Thank you.
