roslyn: `"csc.exe" exited with code -2146232797.` using Version 5.0.100-preview.8.20417.9

Version Used:
MS Build Engine 16.8.0-preview-20414-02+a55ce4fbb
.NET Core SDK 5.0.100-preview.8.20417.9
Steps to Reproduce: This may be reproducable by cloning https://github.com/Unknown6656/Unknown6656.Core and trying to build the project /Unknown6656.Core/Unknown6656.Core.csproj using the .NET Core SDK version 5.0.100-preview.8.20417.9
Expected Behavior: No crash of csc.exe (at least, it did not crash on version 5.0.100-preview.7.20366.6)
Actual Behavior: (I’m so sorry for the wall of text)
Microsoft (R) Build Engine version 16.8.0-preview-20414-02+a55ce4fbb for .NET
