Hi,

I wanted to try out version 2021.10b16 of unity since it supposedly have removed the shader limits which used to be 384 (from 256) in the past, however I ran into compile errors for a ZString plugin, I get a ton of these errors, this all works fine in 2021.1:

Look for a System.Memory.dll in your asset folder and try to delete it (backup before).
