I could not reproduce it. However, when I type open ./C<tab>, the C will get deleted when the menu pops up.

It seems it will happened in the fold of mine, In other fold it won't happened

Emmm, I change the path of the fold of nushell, but it still happened. I think something in the fold make it panic..

I remove the crates fold, It not panic again. I just do

mv crates brates

It stops panic.
Maybe the crates fold make it overflow

Yes, Just because there is a file or fold begined with c it panic

I fond it will happen when meet uppercase and lowercase at the same time. Any char is ok.

I can reproduce this with the steps above. Thanks!

To reproduce on macOS, open up the latest main in the nushell source directory and do the same steps: open ./C<tab>
