Occasionally when I come to a stop and have the auto start/stop engaged, the engine cuts off as expected but there is also a "chirp" and both blinkers flash once. The chirp and blink only happen occasionally and the engine restarts fine after letting off the brake. Does anyone know what's going on here?

Hmmm.... No issues for me. I'd try to document (video) it and head t the dealership.
Goodluck.

I don't experience that issue, but I do get something somewhat similar.

When I start my engine, if my key fob is in my pants pocket, I ALWAYS get the double chirp (and a dash message - no key detected). HOWEVER, if I toss my key fob on the center console (nearby the USB ports), I never get the double chirp.

It's odd... and irritating.

My 21 Badlands just started doing this. It's not all the time and usually when the engine stops, not when it starts back up. There are a few other threads discussing it, but no specific answer / fix. I'm going to check the grounds on the fuse boxes and look for any moisture on harness connectors in the dash. I had tint/ppf done, so that may be an issue. I'm also going to fire up Forscan and see if there are any codes.

Interesting. Same here; chirps sometimes when shutting off but never when restarting. Please let us know if you see anything on Forscan.

Tightened fuse box bolts and checked codes. I had a few codes, but they looked to be related to when I installed my spare tire delete and had the brake light and camera disconnected. I ran tests on those modules and no errors found. I cleared the codes and will wait to see if the flash on engine stop happens again. If it does, I'll check for codes again.

Start stop is the most annoying thing I ever experienced in any vehicle. So glad I can disable it

This is happening to me pretty regularly. Did you ever get any response? I’m trying to track more posts down on the forum but it’s hard to find.

Try start/stop with a manual and a quiet exhaust. I tried to forscan it off and nothing happened. I used forscan to eliminate double honk with no issues.

There's an update from Ford now but it's not OTA - you'll have to take it to the dealer.

Installed Auto Stop Start Eliminator today. 15 minutes, easy to install, and don't have to worry about disengaging. I recommend the install for those interested.

Autostop Eliminator for the 2021-2022 Ford Bronco
I was wondering if the connectors are the same for the parking sensor button and if this would work on that button to eliminate having to push the parking sensor button off every time I start the vehicle.

beyond me, suggest you contact Auto Stop Start peeps to ask.
