Sorry to hear that you still have problems.
I now remember that I did not flash the bios by just clicking on the EXE file. I did it through CMD.
If I run it directly by clicking on the file, a CMD window opens but nothing happens.
You may try the following. This is what I did.
Open CMD (command prompt) with admin rights.
Then change directory to where the bios is located. I have copied mine to C drive to the folder called: C:\AMD_Radeon_VII_bios_v106_x64
Type the bios name and press enter. For me the bios file is called: AMD_Radeon_VII_BIOS_V106.exe
Below is a screen shot where I executed this file again today in the CMD. For me it gives message "Flash already programmed" as I already have this bios version running.

Here is the log file that I saved after I programmed the bios on my Radion VII some weeks ago.
It should show you something like this after successful programming.
