Hi Satya, you probably already fixed this issue for yourself but for anyone that is encountering the issue now, I fixed this issue by checking all dependencies of the project itself and the libraries that I had in the project.
We got this error after a migration from on-prem to cloud and after re-compiling all library items and updating all packages to at least 2021.10+ the issue was fixed.
