Questions about Thunkable

I have noticed my Android app is showing a significant uptick in crashes. I have 49 java.lang.IllegalStateException crashes with my Android app. Here is the specific text from the Google Play console:

I am not an expert in Android by any means, so I have no idea where to zero in on what is causing these crashes. Flipping through the crash data, it appears to crash in both Android 11 (SDK 30) and Android 9 (SDK 28). Has anyone experienced this before? If so, did you figure out what was causing the crashes? I haven’t had anyone reach out to me for support, so I don’t know how big of a concern it is, but seeing the crashes popping up makes me want to investigate it and figure out what is causing the problem.

Edit: After more digging, it is also showing up with Android 7 (SDK 24) and Android 7.1 (SDK 25); albeit less frequently. I assume that’s because a majority of my users are using newer devices.

App made on thunkable?

Yes.

I loaded the APK into Android Studio and let it run for a while. I had no issues on two different emulated devices. I don’t know if this is something I need to be concerned with or not, but I only had a handful of crashes before I released my v4 which was with the new AAB requirement. I have had a total of 79 crashes in the past 60 days. I would not have known about them unless someone contacted me with issues, but I was checking in the Play console and noticed all of these crashes.
