LibGit2Sharp crashes on dotnet runtime 5.0.9

[RonnyB71]

Describe the bug

Version 0.27.0-preview-0034, the version of LibGit2Sharp we are currently using, crashes on calls to RetrieveStatus as described here: libgit2/libgit2sharp#1884

To Reproduce

1. Open and log in to Altinn Studio
2. Click edit on an app
3. Observe that the app crashes when using dotnet runtime 5.0.7 & 5.0.9 with:

An unhandled exception of type 'System.AccessViolationException' occurred in LibGit2Sharp.dll
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Additional info

Version 0.27.0-preview-0100 is addressing this issue and we have confirmed that this resolves the problem in our case as well.

We have previously downgraded LibGit2Sharp from 0.27.0-preview-0096 to the version we are now running. We need to make sure the reason for downgrading then is addressed now and doesn't introduce new issues.

Testing

• run all regression tests covering creating apps, changing apps (ux, data models, resource texts) - in short anything that triggers changes in the underlying git repo.
• Other issues that should be covered/checked out:
  • Bumping designer container to latest dotnet core version causes issues with libgit2sharp #6424

Duplicate of #6424 ? This is probably better described. Consider closing one of them.

@lorang92 I don't think it's a duplicate. At least the error messages are different OutOfMemory vs. AccessViolationException. Might be that this update also fixes the other one, but we should verify it at least.

Didn't @SandGrainOne find a thread that describes how how the new preview resolves some issues? Could be nice to have a link to that here :)

test is complete in staging studio on all the git operations (push, pull, delete local changes, solving merge conflicts)

Still experiencing memory issues when bumbing dotnet runtime. Others are reporting the same issues: libgit2/libgit2sharp#1872
dotnet/runtime#50739

Bumping libgit2sharp causes trouble with interacting with the repo, e.g. gettings status and push/pull

Designer now running with mcr.microsoft.com/dotnet/aspnet:5.0.10-alpine3.14 AS final. Closing issue
