Distant Horizons server plugin console error

I am using "DHS-0.8.1_for_MC-1.20.1.jar" in my modrinth server and it is throwing the following error (see image)
It also keeps spamming the console with: "WARN [DHS] Could not delete LOD world -22x5"

Did you use an older version of DHS before?

"Unsupported class file major version" means it was compiled with a newer version of Java than what you're using, or more likely; than what the server's bundled version of ASM supports.

The warning about LOD deletion is fixed in latest nightly
