Hi, I found some issue with flashing process.
After the new firmware was successfully updated, there is no window 'Apply defaults defaults'. Here is a short video 

Build 4.3.2 and hex file (loaded manually . needed for ELRS 3)

betaflight_4.3.2_CRAZYBEEF4SX1280.hex
Source: https://github.com/betaflight/betafli...

Unfortunately there is no option to ''Apply Custom Defaults' .
Now my baby is bricked, I tried to load backup , no luck.

Short video: 

I've checked my backup :

You can find the custom defaults for this board here and manually paste them in the CLI:

Issue solved, I got support from the 'happymodel' team:
This is what they told me to (2 files attached)
Just roll back the firmware to 4.3.1 and then load the default factory setting, i have attached all .

Official files from happymoidel 

Mobula7  4.3.1 with ELRS 3.0
PFA attached files.
Tested . Works fine
