ERROR MESSAGE [Marlin\src\HAL\AVR\HAL.cpp]

Trying to compile Marlin 2.0.x for Anet A 8. When I add in the config files for an ANET A8 and try to compile, I get the error message "[Marlin\src\HAL\AVR\HAL.cpp] E:\Marlin-2.0.x (1)\Marlin-2.0.x.pio\build\sanguino1284p_optimized.sconsign39 .dblite: No such file or directory".

Looking for a way to correct this problem.

Thanks in advance for any solutions
