✅ ASP.NET Core Web API application crashes with no error message only in some environments

I am working on a Web API project which runs fine in Docker and on a Windows machine, but crashes with no error message and an exit code of 139 (segfault) on Linux. What troubleshooting steps should I take?

also when i run the app from the executable in bin/debug/net6.0, this pops up

Failed to load /usr/lib/dotnet/host/fxr/7.0.8/libhostfxr.so, error: /snap/core20/current/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by /usr/lib/dotnet/host/fxr/7.0.8/libhostfxr.so)
