Hello,
This is a known issue and has been reported to VS team, please refer to jfversluis's comment and follow the progress at Allow building, running, and debugging a .NET application in a long path - Developer Community.
(I noticed that you added both Xamarin and MAUI tags, and I removed the Xamarin tag since Xamarin support has been ended and your project is target on .NET8. Also, Xamarin.Firebase.iOS.Crashlytics NuGet only targets on .NET6 and has ended their support, you could try to find other third-party packages).
Best Regards,
Wenyan Zhang
