I have tried again and again to make an owmdl work with vrchat, most of the time in blender it just crashes or the SDK doesn’t work properly. Any ideas?
Hmmm it’s hard to help you out - keep in mind that this is the official VRChat forum, so people might be reluctant to help you import third-party models. Those are sort of a gray area.
Best I can say is that there’s lots of resources on how to create avatars on YouTube and in the official docs. Creating Your First Avatar
If you need help with something specific, I think you need to give a more specific description of your issue.
