Error Importing Gmsh

I pulled the latest changes from the develop branch locally and when attempting to import a Gmsh *.msh file I get the following error:

SyntaxError: invalid syntax

Is this an issue with my environment, or is there a syntax error that was introduced recently? Thanks!

I believe this syntax requires Python 3.11 or newer.
