Hi, I am an Independent Advisor.
I'll be able to help you with this issue.
I understand that your OneDrive is creating folders on its own and uses a different language.
Have you tried logging in to OneDrive.com and check if those folders are visible from there?
Have you tried signing out and signing back into OneDrive?
What happens when you manually delete the unwanted folders? Do they come back?
Please try to scan your PC using your Windows Defender or your Anti Virus Software.
