Describe the bug

Watching videos as normal, try to load a video page, watch the spinner spin for about a minute then the error is thrown. This has only happened twice since the update which I applied the day of release. Requires an app restart to fix
OS is Graphene, stable build. WebView in settings shows the following "exploit protection" settings which are unique to GOS:

Hardened Memory Allocator: Enabled
Extended Virtual Address Space: Enabled
Native Code Debugging: Blocked
WebView JIT: Disabled
Dynamic code loading via memory: Restricted
Dynamic code loading via storage: Restricted
