All my WSL2 windows have "WARN:COPY MODE" on them. What does that mean? Is there an error on WSL2 that I need to correct?

Thank you,

John

    This is stock Dell 7720. Only thing not stock is that it is dual boot with Ubuntu Unity 25.04 and SSD has two exFAT partitions for my files. They can be accessed by both Ubuntu and Win software.

How about a screenshot? I've used WSL for years with no issue.

Thank you very much for your reply. "WARN COPY" shows when more than several wsl windows are open. For example, evolution, nemo, libreoffice, and pdfstudiopro 2004. I use Win 11 for MS EDGE or firefox. I suspect I am pushing the limits of wsl. I am on extended business trip so now is not the time for changing the pc.
