Not compatible with 1.16.1

[Blite33]

When I open fabric 1.16.1, it crashes after the launcher finishes readying the game for launch. It says runtime error in the launcher.
Here is the error:

No plans to update Fabric atm, 1.16 made things more complicated and it'd need more work than expected. I have updated Forge for the moment, so if anyone has the time to port all the changes I needed to make, PRs are welcome.
