I randomly get this crash in my webview application when loading data. There is no pattern to it, it can happen in all areas where images are being loaded into vram.

Here is the error: 2023-09-16 19:57:55.404378+0200 Bluelife[3284:194440] [Process x10d004350 - [PID=3445] WebProcessProxy: :didClose: (web process 0 crash) 2023-09-16 19:57:55.404500+0200 Bluelife3284:194440] [Process] 0x10d004350 - [PID=3445 WebProcessProxy::processDidTerminate0rFailedToLaunch: reason=Crash 2023-09-16 19:57:55.404579+0200 Bluelife[3284:194440] [ProcessSuspension] 0x10c01dfe - ProcessAssertion: Failed to acquire RBS Background assertion 'XPCConnectionTerminationWatchdog' for process because PID 0 is invalid 2023-09-16 19:57:55.410251+0200 Bluelife[3284:194440] [Process] 0x130856218 - [pageProxyID=14, webPageID=15, PID=3445] WebPageProxy: :processDidTerminate: (pid 3445), reason=Crash 2023-09-16 19:57:55.411392+0200 Bluelife[3284:211863] [ProcessSuspension] 0x10c01dfe - ProcessAssertion::acquireSync Failed to acquire RBS assertion 'XPCConnectionTerminationWatchdog' for process with PID=0, error: (null) 2023-09-16 19:57:55.424321+0200 Bluelife[3284:194440] [Loading] 0x130856218 - [pageProxID=14, webPageID=15, PID=3445] WebPageProxy::dispatchProcessDidTerminate: reason=Crash

I have the same issue but only on my macOS app, on iOS works fine. I have a published app that used to work ok until I upgraded to macOS 14.

I created a test project (SwiftUI) with a simple WebView in it and it worked. So, I ended up recreating the entire app project and WebView is working fine. I still don't know what caused this but now it seems to work.
