I confirmed it works in 2.10.28, 2.15.30, 2.18.16, 2.23.15. Broken in 2.28.11.
I've reverted 2.23.15. Razor syntax highlighting still doesn't work at all, but at least the whole LSP server doesn't crash and break regular .cs files too.

@TrieBr would you be able to enable crash dump collection by setting dotnet.server.crashDumpPath to a user writeable folder in vscode settings? That should hopefully create a crash dump. You can email the dump to me directly if you don't want to share publicly ([email protected])
from vscode-csharp.

@dibarbet Did you receive the crash dump? I'm having the same issue, can generate the crash dump if needed.

Was able to reproduce today on a devcontainer, and figured out the issue thanks to dotnet/runtime#79832
Issue appears to be our usage of memory mapped files - these files are getting stored in /dev/shm in the docker container which by default is given a max size of 64MB. We quickly exceed this value. Can view this in realtime via the command watch --interval=1 df --human-readable /dev/shm to see the usage of /dev/shm slowly go up to 100%, at which point the server crashes.
Currently exploring a fix for the issue, but in the meantime you can start the container with a larger /dev/shm size by passing --shm-size=4G to docker run (or adding "runArgs": ["--shm-size=4G"] to your devcontainer.json
