session freeze during linux nano edit of a file

[DougSmythies]

I communicate with various linux computers via OpenSSH_for_Windows_9.5p1 from my windows 11 computer. I edit files on the linux computers using the nano editor.
Sometimes after a copy and paste, the nano session freezes. I have to close the terminal session in windows and start again, often loosing the edits done prior to the freeze. I have tried every keystroke I can think of to try to get the session unfrozen, but so far nothing has worked. As far as I can determine the nano task seems to still be running.
How do I know the problem is on the OpenSSH_for_Windows? I don’t, and am pursuing the issue from the Ubuntu linux side also. Regardless, if there is some way to “kick” things out from being frozen it would very useful.

A couple of screen shots are attached.

EDIT:
For the same file:
nano 7.2 on Ubuntu server 24.04.1 fails.
nano 3.2 on Raspberry Pi passes.
nano 5.4 on Debian server 11 passes. <<< Correction: Fails.
nano 8.1 on Ubuntu desktop 24.10 VM guest on the Debian server host worked but pastes “10000~” instead of the copied “10000”.
nano 7.2 on Ubuntu desktop 24.04.2 VM quest on the Debian server host fails.

EDIT: same issue using "OpenSSH_for_Windows_9.8p1 Win32-OpenSSH-GitHub, LibreSSL 3.9.2"
Link to this same issue posted on Ubuntu discourse

EDIT: The root issue seems to be the breaking up of "bracketed pastes" in the middle of the "End of pasted text" sequence. Similar to this bug report , however in my example the paste buffer is only 5 characters.
