 Couple of things I'd check...

1. How are you launching Chrome? Are you running google-chrome[-stable]
from a terminal or just doing Win/Meta and typing in Chrome? If it's the
former, that could be the problem because...

wmcdonald@fedora:~$ which google-chrome
/usr/bin/google-chrome
wmcdonald@fedora:~$ ls -l /usr/bin/google-chrome
lrwxrwxrwx. 1 root root 31 May 24  2022 /usr/bin/google-chrome ->
/etc/alternatives/google-chrome
wmcdonald@fedora:~$ ls -l /etc/alternatives/google-chrome
lrwxrwxrwx. 1 root root 29 May 24  2022 /etc/alternatives/google-chrome ->
/usr/bin/google-chrome-stable
wmcdonald@fedora:~$ ls -l /usr/bin/google-chrome-stable
lrwxrwxrwx. 1 root root 32 Jul 23 00:03 /usr/bin/google-chrome-stable ->
/opt/google/chrome/google-chrome
wmcdonald@fedora:~$ ls -l /opt/google/chrome/google-chrome
-rwxr-xr-x. 1 root root 1585 Jul 23 00:03 /opt/google/chrome/google-chrome
wmcdonald@fedora:~$ file /opt/google/chrome/google-chrome
/opt/google/chrome/google-chrome: Bourne-Again shell script, ASCII text
executable

Or more briefly:

wmcdonald@fedora:~$ realpath $(which google-chrome)
/opt/google/chrome/google-chrome

2. What does lsof say for the parent process/its child processes? (You
could try strace too, but not sure how you'd strace something initiated
from the window manager easily...)
