Macbook Pro freezing after login after installing macOS Big Sur 11 beta 4

Hello fellow devs

I have just upgraded my 2018 MacBook Pro from Catalina to Big Sur 11 beta 4 and since first boot, the whole system freezes after about one minute, the trackpad becomes completely unresponsive as the system completely hangs for about 30second and then the fan goes full throttle for about a second and then the device restarts.

I have checked Activity Monitor (have to open it straight away before the system hangs) to inspect if there is any excessive CPU or memory usage and I can't see anything suspicious.

Anyone have any ideas?

I'm having the exact same issue with a 2019 MacBook Pro. I just updated from Developer Beta 3 to 4.

I have got the bug. After update to Big Sur 11.0.1 MacPro 2018 I have got an overflow used memory after 5 minutes from start building with XCode 11.5. I don't know what is happening, because Activity Monitor is empty, it can't show an info about processes. MacPro is freezing. Touchpad is freezing.
