Renaming both Galaxy dll in the root directory worked for me. Thank you !

While it has worked for me a few times (maybe 3 times) and I could play without problems for a few hours, loading the next day without any changes resulted in crashing again and trying all versions of tricks and multiple additional ones without much success.

So i might have found my problem and a solution for my Black Screen (but it might not work always as before). If you adjust your maximum fps in your graphic card settings to a stable, fixed value (e.g. 30 depending on your setup), it could help prevent the crash in the main menu/at the end of the loading screen. I tested it five times now and the game nearly always crashes with fps set to 60 and never with fps set to 30.

It might also be useful to check your DRAM-XMP-Settings ( ~ how fast your RAM is working) in your BIOS, if you know what you're doing. I'm not exactly sure why it might help here but it has been used to fix problems with black screen/crashes with unity in e.g. Valheim.

Another option is to make a clean boot without *any* non-windows services in the background and check if you can start the game directly with the wrath.exe. If it works, you can restart your system with additional services active one by one to find the culprit.
