Are you confusing anything about Qatar and Covid? Qatar won the right to host the World Cup back in 2010, and it was initially assumed that due to the climate, the championship would be held at such an exotic time. Covid has nothing to do with it.
As for Pogba, he's still recovering from injury (and surgery) and appears to be doing well, but Deschamps said it's not yet clear if he'll include him in the squad.
Normally we don't have world cup scheduled in November-December. For example, Russia 2018 was held in June-July. I thought that the tournament was moved to November, due to COVID. It never came to my mind that Qatar is located in the middle of desert and weather would be intolerable during June-July. Anyway, no one is complaining about the weather in Qatar right now and therefore I believe that the organizers did a good job.
Thanks for the information about Pogba. It is still not clear whether he will participate in Qatar 2022. But one thing is sure. France would be significantly weakened if he doesn't play.
The result of the season (and such an exotic World Cup), in my opinion, can only be summed up after the national championships resume and we will see how such a calendar of games affected the results of the teams. It seems to me that most of the top clubs (whose opinion is the most significant) will be unhappy.
Deschamps has a wide choice, but only he knows who he will prefer - an experienced Pogda who is recovering from an injury, or for example Tchuameni who will be functionally much better prepared, plus he will be more motivated.
