Hello Every one,

I have some issues when exporting a variable font from glyph 4,

It’s a variable font with only one axis of weight, in the file previously I used some ink trap components, but they did not interpolated well and created some kinks, so as suggested by Rainer I decomposed the ink traps and used his script HOI Dekinker to smoothen up the curves during interpolation,

But now the file won’t export at all ( before that it was exporting perfectly ) and showing me this at first:

And now this (haven’t changed anything):

I’m not sure what the first message even is meaning, and the second one not sure how to correct it.

What could possibly the reason?

Here is a screenshot of the M during interpolation (does the red underline mean something?)

Thank you in advance for your help.
