I have just opened my new install of RH2019 (New not Classic) on a Windows 10 machine and I can't get the Properties Panel to display. I select View>Properties Panel but nothing happens.
I haven't installed any updates yet (as it takes forever to get them through my work support process) but this is so basic that I can't imagine it was a bug.
Oh it's suddenly started working! At first it didn't work at all. Then it started to work in reverse. So if I had the tick for Properties Panel it didn't show, and if I removed the tick it DID show. After a lot of generally opening and closing things it has started to work correctly. Bit of a scary start - I hope it's going to be OK - the product looks amazing otherwise.
