Your system is not up-to-date, as all 3 Manjaro branches are currently on Plasma 6.6.4.

Also, Stable branch currently is on version 6.18.26-1 of linux618.

Hopefully the issue will be resolved after you update your system & reboot into the newer kernel & Plasma 6.6.4:

sudo pacman -Syu

or

pamac update --no-aur
