Catalina Installation Stuck on second stage, it just freezes

No - Your Specs are quite high and best suited for Mac Model 19.1, the fault lies else where. Are you running the latest BIOS version for your board? The EFI Folders should not have posed any installation problems.

know about bios version but while installing Mojave I had to adjust date back to July 2019, so I said. Maybe on only newer models Catalina can be installed.
How to update bios btw z 390 m non gaming.

Adjust your BIOS time and date to reflect current date and time, your machine should not have any problem on that score. I suggested checking those time and date checks in the unlikely event that the board reverted to factory settings.
If you do not know how to update your BIOS then I suggest you leave well alone.

At this juncture, I suggest you trawled the Forums for EFI Folders with similar board and specs to your own and try to at least install Catalina. Once you reach the Desktop you can tweak the settings to suit your machine and needs. This is where Google Search comes in handy. Good luck.

UPDATE : while installing Mojave again on another disk, same efi which worked earlier and everything same, I get this error. Do you think i have bad luck ?

I installed Catalina 10.15.4 on the nvme Drive on Windows 10 with the help of your EFI

1. First I changed windows installation from MBR to GPT
2. Then created Partition 50GB for Catalina
3. Then increased size of Windows EFI created by default of 100 MB to 200 MB for Catalina
4. Then installed Catalina
5. Then Renamed bootmgfw.efi to bootmgfw-orig.efi in EFI/Microsoft/Boot/ so the windows option will showup in clover to boot from Windows EFI
thats it.
