When we upgrade any project contains 4.3.48 beta or 4.3.49 beta from 2021.3.0f1 LTS to newer versions, it is not working, and giving the error I wrote below. I tried with both Unity 2021.3.1f1 LTS or 2021.3.2f1 LTS, and I believe it’s caused due to internal jobs/burst package min version required by that unity version. Right now we are only able to use 2021.3.0f1 LTS at max for projects with pathfinding.
Library/PackageCacheemail@example.com/Unity.Jobs/IJobParallelForDefer.cs(77,85): error CS8377: The type ‘U’ must be a non-nullable value type, along with all fields at any level of nesting, in order to use it as parameter ‘T’ in the generic type or method ‘NativeList’
I hope this finds you well and helps you to pin down the problem.
