SIGSEGV: invalid attempt to access memory at address 0x0

[OneXeor]

Hello, I'm new to cpp and I have encountered the following issue and do not know what I can do to move forward. It occurs right after the invocation of the Latent function. Tell me please what is wrong with it or with my code, and how can I fix it?

Some crucial info is missing from that call stack, could you please run at least DebugGame Editor (full "gameless" Debug/Debug Editor preferable if you have one) and look at what exactly is causing the segfault?

In particular, what's the version of UE5Coro and Unreal used and the value of this for the FPromise object before it calls resume() on line 143?

UAuthorisationUseCase is not part of the engine so it's not something I can look into.
