[REQUIRED] Please describe the issue here:

After updating to latest version 8.5.0 app started to crash on Apple devices with iOS 15.1. It happens when I try to convert DocumentSnapshot to dictionary. Everything worked with version 7.2.0.

Relevant Code:

...
        public void Init(DateTime startTime)
        {
            string time = startTime.ToString(DateFormatString, CultureInfo.InvariantCulture);
            DocumentReference PlayerDocument =  FirebaseFirestore.DefaultInstance.Collection("player").Document(_auth.UserId);

            _queueListener = PlayerDocument.Collection("queue")
                .WhereGreaterThan("Time", time).OrderBy("Time").Listen(ProcessCommands);
        }

        private void ProcessCommands(QuerySnapshot snapshot)
        {
            foreach (var document in snapshot.Documents)
            {
                ProcessCommand(document);
            }
        }

        private void ProcessCommand(DocumentSnapshot document)
        {
            try
            {
                var commandDict = document.ToDictionary();
            }
            catch (Exception ex)
            {
                Log.Warning($"Problem in parsing! documentId={document.Id} ex={ex}");
            }
        }
...

Hi @nodrock. Thank you for reporting this issue. We actually just discovered the same issue and spent days investigating! We have a fix that will be included in the next release.

The root cause is an ODR violation where incompatible versions of absl were being used in two of the different binaries. Googlers can check out b/204429003 for details.

Unfortunately, there is no workaround that we know of so you will need to either (a) downgrade to Unity SDK 8.4.0 or (b) wait until the next release, which is planned for a couple of weeks from now.

I'm going to mark this issue as "closed" since the fix is already implemented. Feel free to comment further if you'd like to discuss more. Again, apologies for this bug. It really snuck up on us too.
