Experience crashing 4 times out of 5 on Iphone 13 Pro

Hello Aero Community !

We are currently developing an experience, where the goal is to augmented a complete street, like 300 meters with visuals, 3D rigged stuff and animation all along, instantiated particules animations etc.

We tested multiple files, one making 19,5mo and an other one of just 8,5mo (less things, no particules) but its still crashing 4 times out of 5. How ever, we have a similar structure on both files, the structure remains complex.

We tried to remove different assets, just to see if the file is too heavy, but its seems to be unstable, random, sometimes it works fine and the next five minutes after it doesn't, it makes no sense.

Does any one have already experience that type of issue ? Is there a limitation on the numbers of triggers, actions ? We have optimised textures by crushing them in "PNGYU".

The first Triggers as about 27 actions and the 14 other triggers as about 4 actions each. And the AERO file compte no one less than 27 fbx. Those, are the informations for the smallest project (8,5mo).

We are using Iphone 13 Pro, who is supported device, and the preview on desktop app is working fine.

Lucas.
