it seems

https://trac.osgeo.org/grass/browser/grass-addons/grass7/raster/r.landscape.evol/r.landscape.evol.py#L509

509	    grass.run_command('r.colors', quiet = "True", map = netchange, rules
= nccolors.name)

https://trac.osgeo.org/grass/browser/grass-addons/grass7/raster/r.landscape.evol/r.landscape.evol.py#L522

522	    grass.run_command('r.colors', quiet = "True", map = new_soil, rules
= sdcolors.name)

that the rules fille for these 2 r.colors command aren't correctly defined
in the script.

locally changing these 2 lines e.g. to

    grass.run_command('r.colors', quiet = "True", map = netchange, color =
'viridis')
    grass.run_command('r.colors', quiet = "True", map = new_soil, color =
'viridis')

then the addons script finishes:

r.landscape.evol elev=elevation at PERMANENT initbdrk=bedrock at user1
smoothing=no prefx=levol_ outdem=elevation outsoil=soildepth number=1
statsout=D:\wd\test\log.txt
