Possible workaround:
If you have an AMD card and your driver version is 23.12.1 and Avorion crashes when trying to enter a galaxy please try this:
- search the Internet for "AMD {your GPU} previous drivers", for example "AMD RX 6700 XT previous drivers"
- you should get a search result from the official AMD website (for example: Previous Drivers for RX 6700 XT)
- Download driver version 23.11.1
- Install it
- Reboot
- Try again if you can start Avorion and enter a single or multiplayer galaxy
- Please report back here if this works for you or not, with the exact model name of your GPU.
