Increased crash occurrence in iOS 26.4

Hello. Our application performs encoding and decoding of large json files which sometimes may take up to 1,5GB of RAM memory. We understand that this may be a problem for devices with low RAM memory (3GB). But before iOS 26.4 we didn't have much occurrences (3 for the last 90 days). Starting from iOS 26.4 it started to crash a lot. Can the reason be that iOS 26.4 occupies more RAM memory so there is less memory left for our app? Or maybe starting from iOS 26.4 there is less RAM memory allocated per app? The crash message is

Fatal error: failed to allocate 392 bytes of memory with alignment 8
