I'm not usually a "actually this is the fault of regulation" sort of person, but in this case it really is the fault of regulation. A bunch of states have laws saying premiums can't rise more than X% in a year, or can't rise at all without the approval of the state insurance commissioner. If circumstances have changed (e.g. wildfire or hurricane risk is now worse than we thought, and also labor market tightness and inflation means repairing/rebuilding is much more expensive) such that the insurance company can't insure you profitably without a rate hike they're forbidden to do, then of course they're going to drop your policy.
