If my desktop somehow updates, the wallpaper gets replaced with green color. That looks like this: 
If I right-click and do “Refresh”, the whole background gets green.
I think that has something to do with the second monitor connected to my Laptop. Also, all my drivers are up-to-date, and I run the latest Windows version.
The bug happens at random intervals and I have no idea why.
More information on request.

Sounds like the icon cache got corrupted somehow.
Navigate to
C:\Users\%username%\AppData\Local\Microsoft\Windows\Explorerreplace %username% with your username.
Here you will see a lot of files like iconcache_32.db, iconcache_48.db, iconcache_96.db, iconcache_256.db, iconcache_1024.db, iconcache_1280.db, iconcache_1600.db, iconcache_1920.db, iconcache_2560.db, iconcache_exif.db, iconcache_idx.db, iconcache_sr.db, iconcache_wide.dd, iconcache_wide_alternate.db, etc.
Delete them all to purge and rebuild your icon cache in Windows 10. If you were to be able to delete some of them, you would now be able to see a new folder created named IconcacheToDelete, which will disappear when you reboot your computer or restart Windows File Explorer.
