Replaced the chandelier with an analogue, why?

Question

Data recovery

Hello. Moved from a fork and Adobe Illustrator (chandelier) to Linux with the Gravit editor.
There was no error in the chandelier. but after Linux ..... I run the file and it's stupid but (the screen flickers) as if I have a screen purity of 5 hertz. there is a suspicion that this is due to the layout (character object copied from a file provided by the customer). Moreover, the customer's file is saved and opened without problems, and my file was saved normally, and when opened, it gave exactly the same message.
I tried to find a pattern.
I did it as follows - I copied part of the layout and created a new file with this part. Saved, closed, reopened. If the file opened without problems, I added another piece) And so on ... I found this piece and stupidly drew it myself))
Perhaps symbols from the standard libraries of illustrator (buttons, for example), or some kind of effect ... Here only to analyze if the search engine did not find anything sensible) and did not understand what was going on. The file itself or the program.

Answer 1

I don’t know about Gravit, but there were problems with the chandelier (but they can be solved)
Try: -
open through the chandelier, preferably of the same version
- reinstall the program, libraries, firewood - open
on another system
- open Illustrator via online recovery
- write to off. website
- open with editor
- change extension

Answer 2
