FWDs wouldn't open, couldn't override

There was nothing blocking the sensor; the entire roof was clean as a whistle. All snow had melted the day prior.
Oddly, the screen indicates an obstruction, but doesn't show any sensor reporting one. Further, the doors should *always* respond to manual override. That's the most concerning, as it represents a safety issue when only young children occupy the back seats.

It shows something on top, see the yellow bars. Those look to me like a failure of the sensors down the middle/central beam of the car, if there is actually no dirt/blockage.

Did somebody say BIRD POOP. Yes it will not open with poop on the sensor. HoHoHo.
Not the case here. In fact, conveniently this issue occured as I rolled into a self service car wash (with a 30 foot ceiling) to clean brake dust from my rims. I took the opportunity to spray the roof of the car repeatedly, even though it was already pristine--you could eat off of it. It didn't not help. The doors still refused to budge.
I could imagine a sensor failure. What I can't imagine is why the car would not allow a manual override.
Yeah, usually if the sensors show ‘something’ you get the ‘waves’ near the doors. I get them in my garage from a wall and a ‘bumper’ I have hanging down between two cars.
I’ve never seen the yellow like this which looks like the open trunk/frunk. It may mean ‘unknown obstacle that I can’t see/understand’ and thus won’t allow override.
That’s my guess

You need to clean brake dust off your rims? Do you have regen turned off?
I never get brake dust on the rims... I use the brakes so seldom it just doesn't occur.
edit: formatting
Just saw the car wash note..: not sure how a 30 foot ceiling is an obstacle. Was there really nothing else around to reflect ultrasonics? Was this an enclosed building where perhaps waves could be strangely reflected so that it came back at a weird angle?
Random musings: Any chance there was ice in the seam between the doors and rest of the car? Wondering if the yellow indicated that it could not lift the doors. Did the latches make any sounds?
Yes I had this happen 2 days ago. It snowed a lot so I thought it was ice on the roof but we had the exact same image and the override didn't work for us either. After driving to another location, the FWDs worked again. It hasn't happened again, with more snow and colder temperatures so hoping that's just a one time glitch.
This sounds like the inverse of my issue -> Falcon Wing Door fault with heat
So besides heat issue affecting the sensors, snow also affects them.

In my case, there was no snow present, so we have:
- snow
- no snow (but coldish--mid 30s)
- heat
I'll bet this problem doesn't occur in California. Nothing ever does.
PSA: be extra careful in parking garages after such an event.
One of my FWDs just opened into a thick concrete beam, despite passing under a number of them just beforehand.
I think this means that my roof ultrasonic sensor silently failed before Tesla service could get around to diagnosing the original issue, preventing the FWD height from being restricted.
