After updating the phone, everything has stopped and stuck on a black screen

[AC Question]

So I recently updated my tablet Lenovo Tab 2 A7-30 after it turn on it gives me a lot of notification on the screen that a lot of processes have stopped, you can't click anything else except the OK button on the notification after that another one appears, I cannot shut down the tablet because the notification is in the way, neither can I go into recovery mode because I can't shut it down.I really don't know what to do, any help would be greatly appreciated, I also tried plugging it into my computer but it doesn't recognize the device.

Thanks!

Was it an OTA Update?
