There is a bug in this version that does not load saved FX when in the Fx tab.
both in Serum and Serum Fx

And of course, once when I was working with Serum, after about 20 to 30 minutes of closing and reopening it, a black screen came up and gave a long error message and an error code was written that I couldn't take a picture of. And every time I opened Serum again, it gave that message. Of course, it happened to me once. after closing the DAW and reopening it, it worked properly.
