That's just one, but we are seeing this issue effecting roughly 18% of our app users and we have collected 576 such events over the last 30 days.

This screenshot from Sentry might be helpful in understanding the breadth of the issue:

(numbers are "number of events", so e.g. we have 1k events from iPhone 11)

Hmmm, well I did just get the following in my development environment which seems... suspicious.

So you're using 0.71.13.

https://github.com/facebook/react-native/blob/7399bbbd0252d2935fd015acd4b5b9322c9bdb72/Libraries/Image/RCTImageLoader.mm#L255

Looks like similiar in main:
https://github.com/facebook/react-native/blob/main/packages/react-native/Libraries/Image/RCTImageLoader.mm

There seems to be multiple threads accessing RCTImageLoader, not sure if we're using it correctyl regarding multithreading.

Are you loading a lot of images durng startup?

[vanGalilea]

How can we avoid this, as we're also experiencing a similar issue:

SIGABRT: *** error for object %p: pointer being freed was not allocated

Are you loading a lot of images durng startup?

I am not too sure, @benjamin-sweney can answer confidently. I would think we probably are as our application displays satellite imagery of dairy and beef cattle farms which are several hundred hectares or larger in size.
