Cannot Copy Text from Thunderbird 115.9.0 (64-bit)

I am using Thunderbird 115.9.0 (64-bit) on Windows 11.

I am finding that I cannot copy text out of a Thunderbird window (e.g., an incoming message or a message-composition pane).

If I select text and "copy" (e.g., by context menu with right click or Edit-Copy ordinary menu), my clipboard is cleared.

If my clipboard is not clear (text copied from another application), I can paste that into a Thunderbird message-composition pane. But if I then select that same text in the Thunderbird window and then do "copy" (above), the clipboard is cleared. Pasting (into a Thunderbird window or something else, like Notepad) pastes nothing.

I have noticed this problem only in the last week or so.

I cannot duplicate that. I highlight and copy from incoming message, then open a new write window and select edit>paste and the content is entered as anticipated.

Thank you.

I tried pasting into a new write window, and that worked.

In fact, the problem seems to have gone away now.

I will continue to monitor it to see if it has gone away permanently or is somehow intermittent.

I continue to have this problem from time to time.

It occurred yesterday, but it went away (I think that I quit/restarted TB).

It has happened again today, and quit/restart has not helped.

Viewing message source and copying from there does not work either.

Can anyone recommend anything diagnostic that I can do when the problem occurs to try to figure out what might have happened?

For diagnostic purposed try the following. That will eliminate Thunderbird's addons, as well as some other Thunderbird "features" and the operating systems non safe mode processes in turn

I use Ubuntu and have the same problems. I may migrate to Protonmail
