Can't remove, hide or delete OneDrive account (from prior work employment) on PC's file explorer

I cannot remove, hide or delete a OneDrive account (from prior work employment). The message I receive is:" The system cannot find the file specified."

Any suggestions on how I can hide it from my PC's file explorer? I want to keep using my personal OneDrive account but I would like to hide/delete my previous employer's onedrive from the file explorer.

Thanks.
