Will there be a 21/22 season in Chamonix?
In France in general there will be a ski season. The question is how much you will need your "Pass sanitare" (proof of vaxination etc). Lifts? Resturants? Work (in a resorts)?
The big teltail difference this year is all the rsorts and more importantly the lift companies are doing job interviews. Last year they were hiring no one, even if they were going to end up Very short staffed come (theoretical) opening.
The pass sanitaire will not affect any overseas guests as they need to be vaxinated to get into the country in the first place - they willl have to show proof, so if you are coming have your QR code in both printed and electonic form, saying that I have only showed mine once at the indor section of a charity flea market!
