Today I tried to update some of the dots packages, in particular com.unity.burst 1.3.3 => 1.3.4 seems to cause this exception, but I did noot have the time ot dig deeper

Unexpected exception System.InvalidOperationException: System.InvalidOperationException: Unable to create a SharedStatic for this key. It is likely that the same key was used to allocate a shared memory with a smaller size while the new size requested is bigger
Thrown from job: Unity.Entities.StructuralChange._mono_to_burst_RemoveComponentEntitiesBatch

What does this exception mean exactly?
Has anyone encountered it?
How can I solve it?

Got the same thing today. It looks like 1.3.4 Burst doesn’t work with Entity package.

worked for me rolling back to Burst 1.3.3.

Just to rule something easy out - did you restart the editor after doing the Burst update or not?

I’m now getting this same error after upgrading to Burst 1.3.9.

Anybody getting this error in 2023 (I upgraded from burst 1.8.7 to 1.8.8)? Restarting the editor did not fix the issue.

EDIT: Found a fix that worked for me: Close the editor. Delete the Project > Library > BurstCache folder. Reopen the editor.
