Hi @Kevin Holzmann ,
Welcome to Microsoft Q&A!
What's your specific version of VS? Could you tell us how you open a new terminal?
Please end all Visual Studio processes from the task manager. Then, open the Visual Studio Installer > More > Repair your VS.
You can open Developer Command Prompt for VS and run the command: devenv /safemode to run VS without any extensions, check if the installed extensions affect or not.
If you have any anti-virus software, please temporarily disable it.
Sincerely,
Anna
