This is a known issue, caused by an incorrect installation.
Do a clean install of SketchUp.
Ensure that its folder in the AppData path is deleted [path given in the error messages].
You may wish to temporarily move out personal collections like Materials, Components etc.
I'd delete the whole Plugins folder and later on reinstall my Extensions from scratch.
The fresh install of SketchUp that we are about to do will recreate missing folders etc with proper permissions set...
Here's the only correct way to install a complex application like SketchUp from its installer exe file, very important in the recent versions of Windows...
Do the clean uninstall of SketchUp as outlined above...
Logged in as your normal user account.
Find the SketchUp installer exe file - probably in your Downloads folder ?
Select its icon.
Right-click > Context-menu > "Run as administrator"
Install it...
Test it...
If necessary move back your personal collections...
There is no other good way to install it from its exe file.
Do not do it whilst logged in as the separate administrator account.
f you have admin rights on your normal user account it is NOT the same thing to double-click the exe icon to Run the installer - it must be done using the "Run as administrator" option, which is subtly different.
An incorrect installation can result in many weird and unpredictable issues, from permission problems preventing some random things loading, to shortcuts failing to be remembered across sessions.
A proper installation should avoid these problems...
