dotnet --help -> Segmentation fault (core dumped)

Most dotnet commands I run on my Ubuntu 20.04 system
gives me the error:
Segmentation fault (core dumped)

I tried rerunning the dotnet installation scripts and I tried modifying the stack size with uint -n (as advised on the internet).
(It’s important to note that I was using the backend of an app on dotnet
without any problems, and this error seems to have come out of nowhere.)

I cannot find a solution for this.
What can I do to fix this?

The following commands produce the segfault:

• dotnet -h
• dotnet --info

The following commands do not produce a segfault:

• dotnet (without any arguments)
• dotnet --list-sdks
• dotnet --list-runtimes

I used the official microsoft documentation from here https://docs.microsoft.com/en-us/dotnet/core/install/linux-ubuntu to install .NET and it ran just fine until a few days ago.

EDIT: Upon further investigation, I found out that if I uninstall the SDK I stop getting the error but as soon as I reinstall, it reapears.
