No missing sounds but halion se 3 doesn't play

I’m using cubase 11 and updated since cubase 5. Since 2 weeks im not able to play s90 piano and many other sounds in halion se. I can load it, but when I play theres no sound. Some sounds are playable some are not. Cubase doesn’t give me any errors. I have reinstalled/registered every soundset several times, I’ve also updated to tge latest halion sonic se version.
I use big sur mac os.
Does any body know how I can fix this?
Thank you

I really need help
