Thanks.

You can check smath files with a text editor.
An empty region between lines 520-530 was causing force crash.
Could you please check and inform if this works?

Thank you so much for your effort, you saved my whole day...



These are lines between 520-530.Which line creates the bug? In case, I will encounter this situation again in future, maybe I will be able to fix it myself.

Culprit is occasionaly lines contain >\[REGION[xxxxxxxx]]\.
They usually have some context you did enter.
Some title, some text, an image, etc.
But as you can see in this, it is empty.
I look for them at first, then others.
Don't delete every REGION containing regions.
Don't forget to backup your file too.
Even it is not opening.
