Thanks. I know it is large, but this is part of the analysis.

Tramp has sent the "ssh -l ..." command. As result, it tries to detect
the shell prompt. It fails, because there are escape control sequences.
Pls teach your remote host NOT to send these characters. The Tramp
manual discusses the case.
If your remote shell is zsh, for example, you must add to the remote
~/.zshrc file
