I have observed maybe the same issue.
When launching the digikam appimage:

=END==========================================================
After some googling, I got some hints about apparmor, and sure enough there was
a entry in my /var/log/syslog:
=START==========================================================
2023-12-22T10:41:10.026986+01:00 Desktop kernel: [ 9294.380673] audit:
type=1400 audit(1703238070.021:926): apparmor="DENIED"
operation="userns_create" class="namespace" info="User namespace creation
restricted" error=-13 profile="unconfined" pid=263108 comm="digikam"
requested="userns_create" denied="userns_create"
=END==========================================================
I tried this work around:
sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0
which solved the problem. Digikam now launches normal.
