I follow the Working_with_GRASS_without_starting_it_explicitly with GRASS 7.8.8 (2023), but it did not work as intended. The Python line "gs.message" runs, but the line "gs.run_command('g.region', flags='p')" give me this error:
Traceback (most recent call last):
File "C:\Users\gparada\PycharmProjects\grass_proj\main.py", line 53, in <module>

File "C:\Program Files\GRASS GIS 7.8\etc\python\grass\script\core.py", line 441, in run_command
return handle_errors(returncode, returncode, args, kwargs)

raise CalledModuleError(module=None, code=code,
grass.exceptions.CalledModuleError: Module run None g.region -p ended with error
Process ended with non-zero return code 3221225785. See errors in the (error) output.
I didn't find useful information online to solve my error. My code is:
