SharePoint Site Mapped to Windows Network Drive Fails with Error AADSTS50000

Question

A SharePoint site that is mapped to a Windows computer using network mapping has stopped working. The process used to access it included:

1. Opening the SharePoint site in Edge.
2. Clicking on "Reload Tab in Internet Explorer mode."
3. Opening Windows Explorer and double-clicking the mapped network drive.

Since the morning of April 15th, this process results in the following error upon clicking "Reload Tab in Internet Explorer mode":

"Sorry, but we’re having trouble signing you in. AADSTS50000: There was an error issuing a token or an issue with our sign-in service."

Is this issue being experienced by others? Are there any workarounds available apart from sharing a shortcut to OneDrive?
