Find file related commands hangs when deleting the "~" character

[abougouffa]

Hello,

First, let me thank you for this awesome package which changed the way I use Emacs!

I noticed recently this issue (I'm using a fresh Emacs 30.0.60 build).

emacs -q

Then; M-x package-install vertico, M-x vertico-mode

Then, let's open a file under the home directory:

~/path/to/file.txt

Then, C-x C-w to save the file to another path:

In the completion, press C-a to go to the first character of the path ~, move one char C-f then backspace.

Cursor
 |
 v
~|/path/to/file.txt

When deleting the ~ char, Emacs will freeze for a while (in my case, it freezes and don't release unless I press C-g multiple times).

See the video, recorded on an emacs -q instance, when I press backspace when vertico-mode is enabled, Emacs hangs for a while before actually deleting the character:

Hi @abougouffa! Thanks for the report. Unfortunately I cannot reproduce the problem on my system. I suspect that you might have some file system/mounting issue, where accessing / is somehow costly. After deleting of ~, the file completion table will try to access the root file system at /. If this is not the problem, I'd appreciate if you try to collect more information. You could for example set debug-on-quit and obtain a stack trace, such that we can determine where the code is actually hanging.
