Any ideia how to fix this?

It possible you have too many reference chain in a blueprint, from what i seen it usually happen in widget.

I believe you can increase it stack size via cmp but i have no knowledge on that.

The hard way will be to try to delete some content in hope you can open a project, unless you have some backup project.

Does it happen recently and does it happen on other project ?
