Apparently the linking of /usr/bin/rustc provided by dev-lang/rust-1.80.1 breaks as soon as dev-lang/rust-bin-1.81.0 is installed in parallel. Other version combinations do not seem to be affected.

Could you show me the output of `env`?
Sure, I found the issue in the meantime though: In this case env-update && . /etc/profile was needed. I’m not sure why other version combinations did not show the issue, but still it is fixed. Sorry for bothering the team and have a nice day. If you still suspect something being wrong here, feel free to reopen.
