rustc segmentation fault

[WolfBookyr]

I installed rust with curl https://sh.rustup.rs -sSf | sh. Everything installed correctly except for rustc: stable installed - (error reading rustc version). Cargo and rustup work perfectly fine (except where they use rustc).

Calling cargo run gets stuck with no output and doesn't exit.

Calling rustc --version outputs:
Segmentation fault (core dumped)

Unlike this issue #52772 strace does not fix it.

Is there a way to fix this? Is there any more info you would need to help identify the cause of this?

[nagisa]

If the backtrace is in any way correct, this is caused by some sort of antivirus software. See #56736 for a similar issue. Should report to your vendor rather than here.

[WolfBookyr]

You are indeed correct. Disabling antivirus fixed it. Thanks a lot for the help.
