with nerd-fonts v3.0.0 some material design icons were removed see Changelog. The new icon is an alternative.
You can check for deprecated icons with the nerdfix tool.
Thanks for the notice! Just installed nerdfix with cargo and it works like a charm.
I did run the .tmux file through it and it pointed out the icon.
Will merge the commit ;)
