Stuck at “critical software update is required” screen during startup

Metin:

My MBP doesn’t boot up.

This happened to me after few days of using the new macOS Catalina. When I turn on it says a critical update is required but keeps saying that an error occurred when I try to install.

I’ve tried updating with wifi, personal hotspot and with LAN adapter but I get same screen. I have also tried the clean install with and empty disk (command + R) but shows same screen. I also tried factory OS install (shift option command R) but fails after downloading OS. The NVRAM and SMC reset does not help.

However, I am able to use my mac from safe boot mode but touchbar, keyboard backlight and sound does not work from safe mode. I can also use my mac booting from portable usb windows drive but again touchbar, keyboard backlight and sound does not work (everything used to work from the same usb drive before the critical software thing happed).

The internet says it has to do something with touchbar unit, but I didn’t have any issues before. Do you think replacing the touchbar unit will solve the problem?
