[cmsMake] TypeError: load() missing 1 required positional argument: 'Loader'

[CristianCantoro]

Description:
cmsMake fails with TypeError: load() missing 1 required positional argument: 'Loader'.

I have asked on the Telegram support channel and I have been instructed to use task-maker-rust instead of cmsMake. My understanding is that cmsMake should be deprecated.

Steps to reproduce:

1. run cmsMake

Expected: cmsMake runs successfully.

Actual:

$ cmsMake -a
