Finding the same issue with the pimax crystal, not sure if there is a way to revert the client at least?

EDIT: found the downloads…
tried 1.17, 1.16, both also issues oddly (pretty sure 1.17 was ok for me), went all the way back to 1.14, and its butter.

Yes, you can revert back to an earlier version by reinstalling.

But before that, please ensure you have removed these files and folders.
