Hello, I'm running sketchup 2020 and all of your plugins have recently started causing sketchup to crash all the time. I keep getting these errors. I have attempted reinstalling etc but no luck. any thoughts?

No I was getting these errors and sketchup crashing just this week prior to doing anything. I haven't changed anything with my installs. When I opened sketchup this week it asked me to update fredo6 which I did. I was also having issues with thru paint showing up. So I uninstalled that and reinstalled. It then said my trial expired, so I purchased that. Still was getting these errors and sketchup crashing. Every so often it will crash and then when I reload sketchup all of your fredo toolbars are stacked in the middle of my screen not where I had them. I've had to put them back probably 16 times now. In an attempt to fix things, I did a "repair" install on sketchup, but that did not change anything.

Should I attempt a full uninstall reinstall? anything else I could try before that?

Thank you

It was already set to run as administrator, I had to give permission to repair. I was getting these errors and issues before doing that too.
