Thanks for helping me. I'm not currently running MX Linux. Not sure if I will install it again...

Yes, KeePassXC opens under firejail using the --noprofile option

@mxljw does firejail --ignore=private-etc --ignore=private-tmp --ignore=no3d --ignore=machine-id --ignore="net none" --ignore=nodbus --ignore=protocol --ignore=seccomp --ignore=noroot keepassxcworks?
if so try to remove ignore for ignore to figure out which option cause the issue.
if not try to comment all includes in keepassxc.profile
