Then nothing, probably. Almost all small drones, sold by the literal millions, are made in China, including some used by Ukraine to make Russians less alive. The only notable operational problems I recall from before this is that some drones apparently initialized to recall the last place they were, which was somewhere in China, and would launch themselves in that direction with surprising and slightly damaging results - garage doors was a popular target from testing in the driveway. Plus it took a then quite expensive drone and broke a large bit of it.
The more likely culprit is a problem with the swarming software.
The main maker, DJI, has been very willing to follow the FAA required changes and will automatically download all the keep-out zones in the US, comply with the Remote ID requirements. They appear to understand the risk of being banned.

Of course, Florida:
Can you legally shoot down a drone if it’s “bothering” you? For Dennis Winn, a 72-year-old Florida retiree, the answer has come with a $5,000 restitution order and criminal charges after he shot down a Walmart delivery drone hovering near his Lake County home.
The drone, part of Walmart’s mock delivery trial in collaboration with DroneUp, was flying at about 75 feet when it came under fire from Winn’s 9mm handgun. The former fire captain mistook the drone for a surveillance device targeting his property.
The incident, which occurred on June 26, began when Winn, cleaning his pool, heard a whirring noise. Suspecting surveillance, he retrieved his firearm, aimed, and fired one precise shot, striking the drone and rendering it inoperable. When confronted by law enforcement, Winn, initially unaware of the drone’s ownership, quipped, “I must be a good shot,” according to bodycam footage.
