Garbage collection crash not reported

[mniswander-ca]

Environment

How do you use Sentry? Sentry SaaS (sentry.io)

Which version of the SDK? 0.17.1

How did you install the package? (Git-URL, Assetstore) Git

Which version of Unreal? 5.3.2

Is this happening in Unreal (editor) or on a player like Android, iOS, Windows? Windows

Steps to Reproduce

1. Trigger a crash during garbage collection

Expected Result

Crashes should be reported.

Actual Result

No crash is reported. The last line in the log is LogSentrySdk: invoking `on_crash` hook.

What I think is happening here is that it fails on this line in SentrySubsystemDesktop::HandleBeforeSend(), because it is attempting to create a new UObject, but the engine does not allow you to create UObjects during garbage collection. Which means that any crashes that occur during GC would fail to send.

Any logs or screenshots

This is the relevant tail of the log output.
