When I execute :CoqStart with debugging information enbaled, I get Failed to launch Coq.

Thanks for reporting. Could you try adding print(ver_or_err, stderr) to line 199 of python/coqtail.py, just before the return, and tell me what it says when you run :CoqStart?

It says {'version': (8, 13, 2), 'str_version': '8.13.2', 'latest': None}.
Also, I tried doing the samething with neovim 0.7, and coqtail was able to start successfully. So I guess it has to do with the vim version I was using. I don't know what configuration causes it to break, though.
It seems like there may be something wrong with the Vim-Python channel. Could you try :call ch_logfile('coqtail.log', 'w') before :CoqStart and posting the contents of coqtail.log here?

Ok, so coc seems unrelated. Vim is successfully sending a message to Python, but it's not receiving the response. Try adding prints to python/coqtail.py at lines 865 and 867 to confirm the response is being sent. Something like:
try:
ret = handler(**args) if handler is not None else None
msg = [self.msg_id, {"buf": self.bnum, "ret": ret}]
print(msg)
self.wfile.write(_to_jsonl(msg))
except (EOFError, ConnectionError) as e:
print(str(e))
break
I got this:
[1, {'buf': 1, 'ret': ({'version': (8, 13, 2), 'str_version': '8.13.2', 'latest': None}, '')}]
So it looks like the Python side is sending the response, it's just never received for some reason. Thanks for your help so far but it looks like I'll probably need to do some debugging on my Windows machine, which unfortunately I won't have access to for a few weeks.
In the meantime if neovim works I'd suggest sticking with that for now. Feel free to keep digging into this if you're interested, but I don't have any ideas at the moment for an obvious next place to look.
I finally got around to trying this on WSL and unfortunately I'm not able to reproduce it. So I think I'm stuck unless someone else runs into this and we can get more information about what's going on.
After resolving #316 , I saw this issue. In my case, I was able to resolve it. I had set the b:coqtail_coq_path and b:coqtail_coq_prog variables (to `/usr/bin/' and 'coqtop' respectively). It produced this error:
Failed to launch Coq.
Coqtail experienced an unexpected error. Please report at https://github.com/whonore/Coqtail/issues.
Welcome to Coq 8.15.0
Seeing the welcome message surprised me. Removing it altogether (because coq is in the path) resolved it for me, anyway.
