Options are reset to default when upgrading to 1.16

About 10 snapshots ago every time I load up 1.16 client my setting get put back to default. FOV 70, brightness moody, gamma 1.0. Other versions don't do this only recently with 1.16. It's extremely annoying to change all the settings back to the way I like them every time I play 1.16 after playing other versions. I've had to do this about 20 times now.
