Hi Philipp,
Thanks for the files.
There is a mistakenly copied "export PATH" line in .cshrc. In that shell, PATH is set using setenv.
However, that is somewhat irrelevant, since you have a .tcshrc file (which means .cshrc is ignored).
The end of the .tcshrc file has the 2 errors that I mentioned:
PATH=...
export $PATH
Those 2 lines should be deleted, and replaced with something like:
setenv PATH /opt/homebrew/bin:${PATH}
You might want to verify where python3 is coming from, too. That PATH list does not look quite right.
