Step 1: Provide a summary of your problem
Trying to load the sample session:
https://github.com/tmux-python/tmuxp#load-a-tmux-session
fails with stack trace:

Granted, I did just upgrade a bunch of python libs, but I don't know what specific library change is causing this.
Picked up a new version of tmuxp as well.

### Step 3: Describe the problem:
Updated pip dependencies for another package and tmuxp ceased working.
I rolled back pyyaml to 5.4.1 (was upgraded to 6.0), no change
#### Steps to reproduce:
1. ... copy sample yaml (https://github.com/tmux-python/tmuxp#load-a-tmux-session) to ~/tmp/sample.yaml
2. ... run `tmuxp load ~/tmp/sample.yaml`
#### Observed Results:
- What happened? This could be a description, log output, etc.

#### Expected Results:
Create a tmux session
- What did you expect to happen?
#### Relevant Code:
[I] ➜ cat ~/tmp/sample.yaml
session_name: 4-pane-split
windows:
- window_name: dev window
layout: tiled
shell_command_before:- cd ~/ # run as a first command in all panes
panes: - shell_command: # pane no. 1
- cd /var/log # run multiple commands in this pane
- ls -al | grep .log
- echo second pane # pane no. 2
- echo third pane # pane no. 3
- echo forth pane # pane no. 4
- cd ~/ # run as a first command in all panes
@bedge Interestingly, this works for me (Ubuntu on WSL2)
Can you try this without a tmux config (-f /dev/null)? Without other tmux sessions (-L mysess)?
tmuxp load config.yaml -L test -f /dev/null
If you try that, is anything different?
Any more clues?
@tony
That works: tmuxp load ~/tmp/sample.yaml -L test -f /dev/null
as does: tmuxp load ~/tmp/sample.yaml -L test
tmuxp load ~/tmp/sample.yaml -L "" fails in the same way.
So here's where I remember to add - I already have another tmux session running from before I upgraded anything.
Was there a change with the socket name default handling where not providing a socket name now collides with any existing sessions?
I killed off my many months old tmux to test this theory (something I usually avoid at all costs as I expect do most tmux users), and, yes,
tmuxp load ~/tmp/sample.yaml works now.
...both with and without the existing session running.
I'll close this as a corner case of straddling multi-version configurations. I wouldn't even know how to recreate the issues now.
Thanks for the suggestions.
Thanks for the very detailed response. This issue looks like it'll be helpful if anyone in a similar case happens upon it!

That can cause funky results. You may end up getting "protocol" errors if you do that, it varies case by case
If anything else comes up feel free to mention

Yep, that's the idea - I'll see my own comment when I forget and do it again :)
