Sharepoint 2019 on-prem/Onedrive sign in problem "There was a problem signing you in Code: 0x8004de81"

Question

Need assistance with an error that appears when clicking the sync button from a sharepoint site, which then opens onedrive prefilled with the domain/username. After clicking sign in it returns the error code: 0x8004de81

GPO for "Specify Sharepoint Server URL and organization name", "Specify the OneDrive location in a hybrid environment" set to (Authenticate first against SharePoint Server 2019), and "Silently sign in users to the OneDrive sync app with their Windows credentials" enabled and setup. All have been set correctly, this issue appeared out of the blue with no changes to the GPO. The sync to file explorer/sharepoint was working just fine beforehand.

I am able to sign in as myself with my work email if i open onedrive application by itself (Not by having sharepoint open it), but it still does not let me sync sharepoint files to onedrive/file explorer when i click the button regardless if i signed in prior to that.

Any help is appreciated.
