Classic pro license 2019

My 2019 pro license appears to be inoperative
I was assuming perpetual meant “for ever” but perhaps not?
I do not require support or maintenance, does this mean no use at all?

Perpetual is for as long as the hardware and software at your disposal is able to run it.
How is it inoperative? What is the issue you are having?
Does it not open? Does it crash?
It’s very hard to help without any information.
