Moto Z4 Freezes/Shutting Off After February Update

[GRMotoZ4]

Recently Verizon pushed out a new software update for the Moto Z4. Ever since then, my phone randomly locks up (black screen) requiring me to do a hard restart to turn my phone on again. Sometimes the restarts fails, requiring another couple hard restarts to get it back on. I haven't been able to pinpoint the exact reason it shuts off but so far a Bluetooth disconnect is the most consistent way to cause it even if it's not every time. 

Does anyone else have this issue? Have you found a way to fix it? 

Is there any way to roll back the firmware to an earlier version that doesn't have this issue?

Grmotoza, I rely on my device constantly, so having it complete random actions after an update is very alarming. I will be more than happy to assist. Please share with me what software version is running on your device? Also, confirm for me what happens when you put the device in safe mode?

My device software is PDFS29.105-74-10.

So far I have not been able to reproduce the issue once I am in safe mode but I did have the device freeze on a black screen when I tried to boot into safe mode.

Feb. Update causes my Moto Z2 to randomly shutdown. Driving me crazy!

Same problem with my Moto Z4 after update!!

That's pretty common with Moto phones after an OS update. About all you can do is back up your personal data, factory reset and see if that helps.

Out of nowhere, I was getting messages: "AppFlash is shutting down".  I was unable to use Amazon or Walmart app.  I disabled the AppFlash, but I still cannot use certain apps.

Any suggestions?

I have moto z4. Android version 10

Software updated to QDFS30.130-42-5-10-7.
