Hi, I’m having same issue the menu not showing in maya2023 with pymel v.3.9.7 installed and the plugins loaded. Look like it erroring on cvwrap plugin:
# Error: invalid syntax
# # Traceback (most recent call last):
# # File "<maya console>", line 1, in <module>
# # File "C:\Users\external\Documents\maya\modules\scripts\cvwrap\menu.py", line 68
# # print result
# # ^
# # SyntaxError: Missing parentheses in call to 'print'. Did you mean print(result)?
# Error: name 'cvwrap' is not defined
# # Traceback (most recent call last):
# # File "<maya console>", line 1, in <module>
# # NameError: name 'cvwrap' is not defined
