ADDITIONAL INFORMATION
several months ago kajongg did run on the parent f36 xfce system but after a routine dnf update which updated the kernel the current error appeared. I had tried downgrading the update but to no avail.
I cannot recall which kernel version the problem started at. possibly 5.16.x
last week I setup a ubuntu virtualbox session and kajongg runs correctly so the problem appears to be fedora specific.
the snap install also fails with the same error message. ditto installation using noarch.
