Issue Description and Steps

Please fill in the detailed description of the issue (full output of any stack trace, compiler error, ...) and the steps to reproduce the issue.

I'm seeing lots of crashes on Firebase since updating to v 5.14.0

Maybe related to the refactory to #3423, thread safe issue ?

[dreampiggy]

Someone told me that NSOperation.underlyingQueue is nil, will cause runtime crash.

[guidev]

I haven't checked if #3434 fixes this issue, but my app is available only for > iOS 14, so I don't think that's the issue

[guidev]

This is from Xcode crash reports

[dreampiggy]

These new screenshot seems another issue

[dreampiggy]

@guidev These two crash should be fixed in 5.14.1
