[2023] Mouse Cursor not appearing on main menu.

If you have any sort of cursor customisation in Windows enabled, like mouse trails, turn that off please.

Otherwise please try deleting all Documents/Paradox Interactive/CK3 folders , copying any valued save games elsewhere first.

Good luck!  

Please each of you attach here a dxdiag.txt so we can see if your setups have something in common.

And I assume if you go back to 18.x. it is okay?  

@Ubiquitous_Stank @Thorns82 can I get your dxdiag.txt files too please?
