Already seen a few threads on this, thought I'd pitch in.

Playing Local Play checkpoint against the bots on Precinct Security bugs out after capturing Charlie. The first wave of enemies spawns as intended, coming in from Delta, but the reinforcement wave they get once they start taking casualties seems to spawn and then...disappear? Hard to tell from just audio cues.

Further investigation into the restricted zone past Echo reveals that a handful of them are stuck against walls and jumping in place in the tangle of buildings behind Foxtrot. They still respond to gunfire/noises, and will fire on you if they see you, but otherwise they can't get out.

Interestingly, your friendly bots also wig out. Some of them hang back in spawn permanently, while others start backtracking almost the length of the whole map. Basically, once Charlie is capped and Delta is destroyed, the entirety of the map becomes devoid of enemies and combat. Even counterattacks don't fix it. (Although you can poke around in the redzone and find them once again jumping up and down against a corner like the guy from the Blair Witch Project found a pogo stick.)

Tested on both normal and HC checkpoint. Unknown if it's also happening to actual matchmaking for Co-op. Haven't tested Insurgents Precinct myself, but I hear it's largely the same. Anyone else encountering this?

Edit: Insurgent Precinct is even more bugged, bots are stuck basically from the word go with your allies standing around in the back of the map and your enemies either lodged in corners or aimlessly wandering around.
