It should have started a long time ago.

Description

1. Currently, I am using the latest VS2022 17.12.0, and when building an iOS application on Windows, the build task hangs forever.

2. And through diagnostics, I had found that the process was stuck in the state of extracting GAppM-10.28.0.tgz.

3. Once I kill the 14100 process, the next extraction will finally begin.

4.Look, what have we found? It wants us to agree to whether to overwrite.

Obviously, the extraction has been waiting for a response.

So, the fix is quite simple.

For any stumbling across this issue, there's a manual workaround that allows me to build my project again:

1. Navigate in Windows to the following directory: C:\Users[USER]\AppData\Local\XamarinBuildDownloadCache
2. Look for GAppM-10.28.0.tgz and extract it. If it doesn't exist, you can download it from here: https://dl.google.com/firebase/ios/analytics/4d5ec9a36b6d4fd4/GoogleAppMeasurement-10.28.0.tar.gz. Make sure to extract it to the folder name "GAppM-10.28.0".
3. You should see a file called "GAppM-8.9.1.unpacked" in the XamarinBuildDownloadCache directory. Make a copy of that and rename the file to "GAppM-10.28.0.unpacked".
4. VS should now recognize that the folder now exists and shouldn't prompt for the Overwrite of the folder in the background, which was the cause of the build hang.

Having this error while building MAUI .NET 9 for iOS.

Solved following workaround from previous message:

• Manual extract GAppM-11.0.0
• Create new file named GAppM-11.0.0.unpacked with content: This marks that the extraction completed successfully as the original one
• Problem solved
