No Gyro/ Calibrate Accelerometer is Greyed Out; after updating Firmware to 4.2.11

[SvenL03]

Hello, I have a Nazgul v2 4s. FC:BLITZ F7 V1.1 (IFLIGHT_BLITZ_F722). It was working just fine. I wanted to use Bidirectional Dshot and Blackbox so I updated to the newest firmware: Betaflight 4.2.11. I saved my config. using "diff all" but now I have a "No Gyro" indication and the "Calibrate Accelerometer" button is Greyed Out. The model on Betaflight will not move either. I flashed to IFLIGHT_BLITZ_F722 target which is what diff all said is the correct target. I would really appreciate someone helping. Should I try flashing an older version or a different target? Thank You!
Here is "diff all" before I updated and what I get for "status now":

According to diff you already have had 4.2.11.

Have you checked Full chip erase? Try it with this feature enabled. Then don't restore any config and test gyro.

For anyone who might have this problem...

Corrected information, product name: BLITZ F7 V1.1 Flight Control Basic parameters: MCU: STM32 F722 Gyro:BMI270 Baro: DPS310

You can flash this firmware to solve your problem.
If you contact iFlight online customer service, you can ask the customer service to send you a firmware with this name:
betaflight_4.2.11_IFLIGHT_BLITZ_F722_ShortageSolver_OSR4.hex
This should fix the problem.

You can also try BF 4.3 the latest ReleaseCandidate.

I have an evoque v2 with the same issue. I also have the Nazgul v2 6s and it twitches. I sent it to Iflight and they swapped out all hardware including motors and it still twitches. I just updated my evoque v2 to 4.4 and now it's twitching too! I tried to go back to 4.2.11 and no gyro. Every other version, my quad twitches. I've tried multiple TXs and they all fly the same. Here's a shot of blackbox showing my rear motors at full capacity when I'm doing a LOS flight in my house.
