Try updating your GPU driver from the manufacturers website.
If you have an Nvidia GPU choose the studio driver rather than the gaming version. Pick “clean install” and only install the driver rather than all of the other dross as well. Unless you need the dross 
Good morning @Alexander,
As I see you have a ‘beta’ label, my question is if you installed any PL4 beta version before?
If yes, please, clean everything connected with PL4 beta and then install a commercial release.
If not, please follow the instructions given by @gregor above 
Thank you
Regards,
Svetlana G.
