Getting crash on Throttler.swift line 100

[miralshahvolansys]

Our application is live and we are getting too much crash on Throttler.swift line 100.

Below is the method where the application is crashing as per the fabric logs

	public func call() {
		callbackJob.cancel()
		callbackJob = DispatchWorkItem { [weak self] in
			if let selfStrong = self {
				selfStrong.lastExecutionTime = .now()
				selfStrong.waitingForPerform = false
			}
			self?.callback?()
		}

		let (now, dispatchTime) = self.evaluateDispatchTime()
		self.previousScheduled = now
		self.waitingForPerform = true

		queue.asyncAfter(deadline: dispatchTime, execute: callbackJob)
	}

Below is the line as per the fabric where the application is crashing
let (now, dispatchTime) = self.evaluateDispatchTime()

Below is the crash logs as per the fabric,
