@rose hawk uploaded a log, here's the logs:
It was working a couple of hours ago with no issues whatsoever.
- Fabric 0.16.0 on 1.20.4 with 3 mods
Possible Solutions:
- A file cannot be accessed because it is being used by another process, possibly an instance of the game that got stuck in the background. Try killing all
javaprocesses in Task Manager or restarting your PC. - Update Fabric from 0.16.0 to 0.15.11
