Microsoft 파일 호스팅 및 동기화 서비스입니다.
Hello, thank you for reaching out to Microsoft Q&A.
In this situation, first we have to free up space in your OneDrive storage or we'll have to upgrade it.
To free up space - Go to https://onedrive.live.com/ on any web browser, use an incognito tab and sign in with your account.
You can delete the files you no longer want to keep on your OneDrive cloud storage. [OR] You can back them up to your local storage drive, like Local disk C: or Local disk D:, before deleting them from OneDrive.
Once deleted, empty the recycle bin folder as well.
As your OneDrive account might be frozen, it might take 2-4 hours for the updated storage to reflect into your account.

Another option, you can just upgrade your OneDrive Storage -

The OneDrive basic plan includes 100GB of OneDrive Cloud and 100GB of Outlook email storage.

If you don't want to have OneDrive, you can just move all of the files from the OneDrive cloud to your local drive and then completely unlink your account from OneDrive.
Let me know if you still need more help.
