Im getting this error which is stopping me from compiling my game and entering play mode.
Ive been trying to rig a 2d sprite and don’t think the error is related.
thanks in advance for any assistance!
I fixed it! My dude 
You need to follow these steps:
- Go to your Unity project.
- Go to the Package Manager in the Window tab.
- Downgrade your 2D Aniomation package to preview 5 of 2.1.0
- Now upgrade the Burst package up to 1.0.4 (i think it was 1.0.4)
- Upgrade 2D Animation back to 2.2.0!
Voila! Fixed! (with some issues but WORKS!)
