    Update: After I upgraded our Firebase packages and Ironsource SDK version this seemed to be resolved; not sure which package in particular resulted in the fix.

    Getting this on 2021.3.24f1 as well, running on Mac Apple M1 with MacOS 12.6.4. Workaround seems to be to delete the Burst folder from the PackageCache but this isn't scalable for our wider team.
