There is some additional logs and a repo attached here (did not want this code public) for another crash we saw when using scrypto calls -  doesnt feel the same as this crash because it doesnt produce a crash report, but it was repeatable and occoured at the same spot every time. This crash just recycles the render process, but we have worked around it by using the JS bridge and executing the calls in the host app instead.

We are attempting to get a miminal repo for this crash but its complicated because this is a client/server app and there is alot of mock...

If u have any ideas about possible workarounds - ie. could we pull this code out of ServiceWorker and run it in a normal context to bypass this bug? That will take some effort, but atleast gives us something to aim for. On iOS we have no other option but to use WkWebView, so we are looking for as many options as possible right now.
