this is what happens when Microsoft's detections team is under pressure to constantly deliver new detections: they will just ship whatever without careful evaluation of FP/TP and broader impact
This is what's happened over and over and over, for decades, every time an AV company switched to a new heuristic engine. It has nothing to do with Microsoft being under pressure, this is literally what to expect from AV solutions on the regular. More folks knew this back when AV wasn't tightly integrated into Windows and we all ran at least two different AV applications all the time, but the "a new version is going to flag things it shouldn't" behaviour has been a given for coming up to 50 years now =)
(Which is why you set your AV to quarantine, not delete items, so you can overrule it immediately, make it put the data it flagged back where it belongs, and send a false positive report so the next update, which can be as soon as the next day, won't repeat the mistake)
