Hang risk detected by Xcode 15.3 in Google Utilities framework (GULNetworkURLSession)

Description

Just bumped to Xcode 15.3 and it now reports a hang risk in the GoogleUtilities framework on which depends the Firebase framework.

The warning deals with a call to the NSFileManager API from the main thread in the method GULNetworkURLSession.removeTempItemAtURL (GoogleUtilities>GoogleUtilities>Network>GULNetworkURLSession.m)

For more details, here is a screenshot of the code where the warning is triggered:

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

I have the same problem, and it's causing a crash for about 2% of my users. Have someone managed to fix it?

[1729patrick]

Indeed, I consistently receive warnings about the Network component, yet I also encounter warnings regarding the GoogleDataTransport without experiencing any crashes.
