Wouldn't let me edit the above - apparently too many minutes went by.
I had to do some searching on the net to find a post that had a link to the 2020 msi file.
I used the default prefix (.wine) and the default architecture (win64). I then used winetricks to install corefonts, vcrun2019 and the latest .net that showed in winetricks.
I was able to install the msi after that. I started Sketchup2020. I got to a screen requesting I so I logged and when it said I was logged on I closed the browser windows as it said I could. Sketchup had a button for start trial. I clicked that and got to a screen with an open file button and some images across the top. I opened one of those and yes, as soon as I clicked in the picture and yes the screen goes black and only shows the image again when I release the mouse button. I am able to use the middle mouse button to zoom and rotate. When I tried to draw what seemed to me not to be right started. The screen was flash as I moved around, even after what i thought was finishing the draw. I had to press esc to get out of that.
So, if you are not getting that far try using winetricks to install the latest version of .net that shows. i don't have a clue if it matters or not, but since it said to restart windows I did wineboot in a terminal window.
So, this also sound vaguely familiar to something I posted prior, so I looked and found this:

This was in regards to Sketchup 2017.
I don't know if any of this helps or not - perhaps it's .net if you hadn't installed it yet.
