What Type of Bug are you experiencing?

Verse

Summary

I am getting this runtime error in my game:

Verse unrecoverable error: ErrRuntime_InfiniteLoop: The runtime terminated prematurely because Verse code was running in an infinite loop.

Truncated callstack follows:
VerseEngine_multicast?egate?se:$Block (Unknown source) (Source: Unknown(0,0, 0,0))
VerseEngine_multicast?egate?se:$InitInstance (Unknown source) (Source: Unknown(0,0, 0,0))
VerseEngine_multicast?egate:$InitInstance (Unknown source) (Source: Unknown(0,0, 0,0))
VerseEngine_subscribable_event:$InitInstance (Unknown source) (Source: Unknown(0,0, 0,0))

I found out about this on the website that epic games provides to check for runtime errors.

Someone knows a fix? or what the underlying problem might be?

I heared that sinds the recent patch recursive functions are not preffered? (those recursive functions have a await fucntion in them and also the function is a suspends function.

I used to do event binding with await and a recursive function (i will give a example in the steps to reproduce section). Then after update I got a bunch of infinite loop runtime errors so i changed almost all of those in subscribe function. Is this a bug or is this intended?

Steps to Reproduce

Example of an await even binding i was talking about:

BindToWeaponUI(Button : button_quiet) : void =
WidgetMessage := Button.OnClick().Await()
Sleep(0.1)
if(Agent := agent[WidgetMessage.Player]):
Agent.DeleteCanvas()
OpenWeaponUI(option{Agent})
BindToWeaponUI(Button)

Example of the subscrbe event binding i now use:

OnBegin():void=
InstantReloadClass.ClassSwitchedEvent.Subscribe(OnClassSwitchedEvent)

OnClassSwitchedEvent(Agent: agent) : void =
    PlayerInfoManager.RecordPlayerStat(Agent, StatType.InstantReload, ?InstantReload := true)

Expected Result

No runtime error regarding infinite loops

Observed Result

run time error with infinite loop

Verse unrecoverable error: ErrRuntime_InfiniteLoop: The runtime terminated prematurely because Verse code was running in an infinite loop.
