Why does gd crash when i play a level after putting a start pos after deleting all start positions?

[Tysis]

So i've been facing a problem where when i delete all start positions and place a new start position then playtest or play the level the game crashes
It's so annoying when i'm trying to practice a demon and that happens does anyone experience this as well?

Yes, I have the same problem and it's really annoying. I've searched multiple times for solutions.
I think this happens because of object heavy levels. GD isn't really made for levels with insanely high object counts. If you don't have like, the best pc in the universe, GD will crash when saving object heavy levels.
I tried once to delete some levels of my own which helped a very, very little bit.
Other than that, I don't know how to solve this problem, it's very frustrating for sure.
