Cat 12. Escaped character '\M' is not valid

When using the toolbox "ROI Tools - Estimate Mean Value Inside ROI for External Analysis" in Cat12 to calculate the volume of gyrus gray matter of the brain (MRI-images), matlab generates errors about invalid characters.
I use windows 10 and have tried different versions of matlab.
Can you tell me what to do?

Save D:\MRI\Bedriy E.O\ROI_aparc_a2009s_thickness.csv.
Warning: Escaped character '\M' is not valid. See 'doc sprintf' for supported special characters.
