Did you test the latest bugfix-2.1.x code?
Yes, and the problem still exists.
Bug Description
Using bugfix-2.1.x, compiling firmware for the Ender-5 S1 results in an error (as shown in the picture linked below). The issue is resolved by removing line 2745 in configuration.h "#define LCD_LANGUAGE zh_CN" leaving just the single language line of "#define LCD_LANGUAGE en". I was able to successfully compile my firmware after deleting that line.

Actual behavior
I was unable to successfully compile the firmware until I removed that line.
