An Internal error has occurred

[Enricopez]

There have been many improvements with the latest update, but a bug remains (?: 0: attempt to perform arithmetic on field '?' (A nil value)) when making changes to the photo while leaving the masks panel active.
Let me explain ... when I edit my images I use the masks option a lot (like radial filters or gradual filters). If I leave the masks panel open and try to use "Color Grading" or the "basic" panel, it invariably brings me the error message (as per the title).
To prevent this error from appearing, I just close the mask panel, at that point everything works perfectly. This is not a big problem, but a slowdown because it forces me to do two more passes.

Is there any chance of being able to fix this bug?

Thanks in advance
