Value cannot be null

Hi folks,
Suddenly I have this error which comes and goes randomly


Don’t really know what it is.
I think it’s in ver.2.2.9
It comes when I use the ppm file directory as the work directory.
I have it in a removable drive but the path is fine, maybe the reaction time when it’s in stand-by ?
Thanks,
Andrea

Have you tried changing to another location?

Yes, if I bring it local no problem. I fear it may be the path too long.

I do not remember any changes to this part of the code in the last version of PrePoMax.

May I close this topic if it is related to the USB drive?

You may indeed, thanks
