f31 kde/plasma update breaks 2nd desktop

[Adrian Sevcenco]

Hi! I just updated my laptop f31 and after reboot the 2nd desktop color is gone (now is black)
and the Desktop folder is not longer recognized (globally). (but somehow is shown if the Location is set to custom location)
somehow : the .desktop shortcuts are not recognized as applications

Did this happend to anyone? any idea about the reason (and fix)?

Thank you!
Adrian
