Windows Virtual Desktop (WVD) reports errors saying you are low on space or are out of space.  This can result in difficulty logging in, errors when using applications such as those shown in the following screenshots, and "the cloud operation is invalid" message when interacting with files in OneDrive.

Trouble logging in:

Teams and Outlook errors:
 

Each user is allocated 5 GB in WVD.  This 5 GB includes anything locally stored in the user's profile such as cached OneDrive files, cached Teams info, web browser caches, etc.

If you cannot log into WVD to execute the following step due to a profile error preventing you from logging in, open a ticket with a screenshot of the error message.  Otherwise, if you can log in but are getting error messages when trying to open files or use applications, try the following steps.
