Why fast opening multiple files crashes my game?

My game crash for weird reason I noticed very strange behavior, the game crashes when user flips fast. The game has icons, every an icon is images folder, when user clicks icon, the game load images from the folder and creates thumbnail and displays the thumbnails on another half of screen, so player can choose an image to play. When player clicks icons fast jumping from icon to another, the game crashes, and while if he does that slowly, the game work perfectly. I test my game and followed the code line by line, I'm sure the problem is not my code, Any one has solution or face same problem before? I use c# and loading is sequentially, image after image, I use Async/await and Task(no, async and task are not the problem, I removed them and same problem), now I use task. Delay(100) to hide the problem, but it's not the solution, any explanation for this?

Definitely some kind of devilry. What to do? Put all the icons in one file. It definitely won't be superfluous.

(Sorry for possible mistakes, I use an online translator)

Do you get any errors in the Godot console when the project crashes?

It might be that something is trying to access the texture before it's loaded, and so that's why it's crashing. If so, a potential solution could be checking for null before trying to use any of the textures.

Thank you all, I got the answer from another place, the problem is called "a race condition", this means godot is busy with something(changing sprite texture for example ) and you ask it to do a mission with the same thing(changing sprite texture with different resource) while godot did not finish its first job , godot can't do your mission and crashes. The solution is waiting till godot finishes its first job then waiting for next frame to ask it for next job. In simple words, don't do the same mission on the same object more than one per frame, next mission has to wait for next frame. My mistake was changing object texture by default texture then with new texture in the same frame, now I delay texture changing to next frame using timer and call_deferred function and it works fine. I hope this will help someone.
