DH 1.20.1 2.0.1a is not launching.

Hi, I have been using this version of distant horizons for quite some time now. And now today, this version no longer works for me. When I try to boot up MC, this image below is the error seen. I had about 10 other mods in there, which I haven't touched, and I tried Distant horizons by itself, and the same error appears. I use the latest version of fabric with sodium.
