@sheikah said in New Client 2023.6.0:

For those who are running on windows 7 changing the .vmoptions file in your client installation and changing the line -XX:+UseZGC to -XX:+UseG1GC should allow the client to run

I am running on a pretty dusty windows 10 setup and that helped me as well, thank You very much Sheikah!

Also Thank You robotcat for pointing out that the file is in
C:\Program Files\FAF Client\
