Found where is the problem. Problem is the spaces in filename!!! In 2023 is this still a problem for programmers?
I fixed this issue by adding this line at begging of function check_valid_filename in MKSOutputDevice.py:
filename = filename.replace(" ", "_")

where and on what line did you write that?
I tried it like this and Cura gave an error loading the plugin.
