Issue with mod Up and Down and All Around

[MJ26gaming]

if you try to run that mod using this version, it throws error code 0

The mod is known to be incompatible. It does mess with the camera. The most you can do is send a log of the crash with vivecraft to the mod developer. At that point it's up to them to fix the issue if the 1.12.2 version of the mod is still supported by them.
