However, errors do come up that restrict such syncing, and one of the virtual errors is 0x8004de45.

This error, in general, involves problems with the user's account or with the settings of OneDrive, which block the user from signing into OneDrive or syncing files as such.

The OneDrive error code 0x8004de45 usually occurs when OneDrive is not able to verify your Microsoft account for several reasons that may cause it. Common causes might include older versions of software, incorrect account information, problems with cached account credentials, or conflicts with other apps.
