Okay done. Right after choosing my USB Stick in Clover I get this displayed:

I tried it with the iGPU

Try disabling IGPU in BIOS.

I thought using the 4th post it should be no problem to use the iGPU only. But now I inserted the RX 5700. And I'm getting further than before. I tried with and with iGPU enabled and disabled. For both I get this result:

First it stops here and after 10 seconds or so the prohibitory screen comes

I don't know if your motherboard video out port needs patching so to avoid that possibility, it's easier to just use a dGPU.

Is that all there was to the verbose? I don't see any errors.

Edit:
Did you add "agdpmod=pikera" boot argument?

Disable IGpU and add SSDT-EC.aml to Clover/ACPI/Patched folder.

 

[mroldskool90]

Yes, that's all. It stops after 7 seconds

Disable IGpU and add SSDT-EC.aml to Clover/ACPI/Patched folder.

SSDT is already in there if he's using my EFI.

Added SSDT-EC.aml to Clover/ACPI/Patched and disabled iGPU. Same result.
Removed it and set the iGPU back to AUTO.

Added "agdpmod=pikera" now, but same result, too

maybe ECO to EC there are 3 of the EC fixes usually only need ssdt EC.
Check the thread for the EC fixes.

You don't need SSDT-EC.aml. I already have SSDT-EC-USBX.aml in there.

Leave the "agdpmod=pikera" in there so you don't encounter black screen condition.

I didn't see any errors in your verbose. It didn't stop at "apfs_module_start:1683". It already go past that.

I don't know why it's stopped... Can you try recreating your USB installer?
