Hello I had the same brightness problem. The problem was solved by simply changing the refresh rate of the display in the settings from 60 hertz to the maximum supported for my monitor of 170 hertz.finally got it working. did took a long cut of downloading and installing the recovery of CATALINE 10.5.7 and then updating via beta profile. but its here, finally.
People should remember to leave their system do the work if they have not added the BOOT ARGS: "agdpmod=pikera" the installation happens on its own. when you don't see the mac Installation and only see mac as boot option in the open core menu, you know that its good to go. now you can either add the option and you will start getting the display as mentioned before.
The only issue I have is that I find the brigthness low even after 100 % at hardware level. what can the be issue here ?

Thank you all for your work, without you guys I would not have solved this problem. For 5 days I tried to find a solution, but it turned out that the case was in the GPU.
