Assuming your numbers are correct, add 20 out of 2852 theaters, had issues. That’s not a conspiracy.
The per theater average of the film so far has been a few thousand dollars per theater, so even if 20 theaters were down an entire day, on its business per theater average day (which was July 4th), this would have equated to 5407 (theater average) x 20 which equates to 108k or so of lost revenue.
That’s not enough to have any major effect on a movies overall revenue.
As I said, this is more likely the folks who went to see this movie were more prone to report the fact they had issues on social media, and claiming conspiracy and the right wing media sights were more than happy to run with it to get eyeballs.
I am sure that this was hardly the only movie that had issues in theaters with HVAC that day.
Could there have been an individual rogue employee here and there playing games, sure that’s possible.. but the idea that AMC corporate ordered this across their 547 theaters in the US is laughably absurd.
Don’t have to take my word for it, here are the returns:

The 20 number is the approximate number of comments saying the same thing happened as the Tic Toc poster that put up the video explaining what happened to her. I don’t know if any are true. Did a search and found lots of other reports of issues like fire alarms going off, lights not being turned off, sound not being turned on, a different movie being played. Maybe it is just normal problems and nothing more. The movie is very controversial though. How a movie portraying pedophiles and child traffickers in a bad light can be controversial is still another question.
