Keyboard media keys does not work after update

dell keyboard
media keys does not react after update, e.g. sound volume, print screen, etc

(update: i found that i lost my “custom” key pattern, i.e. Win + L = Lock screen, i forgot which program was related, after trying in “Devices => Keyboard”, it’s not “lost”, it can be detected in there but just simply cannot activate)

(forget to put some log here)

found that hydrapaper in flatpak could be struggling with the keys
i have uninstalled the flatpak version since i found that hydrapaper is just in the official repo now
uninstall all the hydrapaper flatpak dep
install the hydrapaper from official repo
reboot
then the keys are back

my guess would be the gnome flatpak dep could be conflicting (just my guess anyway)
