Wireless android auto randomly disconnect from the car

I have a Mi 11i with weekly beta rom (release 22.6.1) and I have a problem with wireless Android Auto, when I use it randomly disconnect from the car, sometimes can happen multiple times, sometimes it doesn't happen, I tried with different phones to see if the problem was the car but this issue appears only with my Mi 11i. This issue was present even in the older version of the weekly rom.
Is there a solution?
Sorry for my bad english.
