iOS 17 Crash - UIGraphicsBeginImageContext() failed to allocate CGBitampContext

[eduardzurin]

We have encountered an issue in our application affecting users on iOS 17. Our users experience crashes due to the deprecated use of UIGraphicsBeginImageContextWithOptions in the HTMLAttachmentRenderer. As UIGraphicsBeginImageContext is deprecated in iOS 17, it sometimes throws errors under certain conditions:

Fatal Exception: NSInternalInconsistencyException
UIGraphicsBeginImageContext() failed to allocate CGBitampContext: size={-1, -1}, scale=3.000000, bitmapInfo=0x2002. Use UIGraphicsImageRenderer to avoid this assert.

Is there a way to avoid these types of errors, perhaps by replacing UIGraphicsBeginImageContext() with UIGraphicsImageRenderer?

@AliSoftware i also faced to this issue. This happens when we try to paste html with image.

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UIGraphicsBeginImageContext() failed to allocate CGBitampContext: size={361, nan}, scale=3.000000, bitmapInfo=0x2002. Use UIGraphicsImageRenderer to avoid this assert.

I guess the reason may be due wrong size values (here is nan)

Step to reproduce this issue:
Copy text with image from here: https://feature-sliced.design/ru/docs/get-started/overview and try to paste it into editor&&&

@AliSoftware i also faced to this issue.

Thanks for reporting!
I'm not working on this project so pinging @jkmassel to either look at it or delegate it to someone in their team
