New Fedora, new VMplayer startup problems

With older machines we have the risk of unsupported software hitting compatib ility problems with each OS upgrade. A recent example of this is running vmplayer 12.5.9 on Fedora 30 which ran fine on Fedo ra 26 .. 28 albiet needing a couple of tweaks

But what's the new problems on Fedora 30 and what are the workarounds?
