Force stop the app, restart the device, update the app and Android, then clear the app cache. Clear storage or uninstall only with credentials and synced data available because either can remove local app state. Note the app version before and after updating, since a crash that began after an update points to that version.

Exact questions
Common questions about “An Android app keeps crashing or will not open”
What does clearing cache do?+
It removes temporary files without touching your data. It is a safe first step for a crashing app.
What does clearing storage do?+
It removes the app's data and signs you out, so back up anything first.
Can an Android system update cause crashes?+
Yes. If crashes started after an update, check for an app update or a WebView update.
Should I update the app and Android?+
Yes. Updates often include crash fixes.
Would clearing storage help?+
Clearing the app's cache or data can fix a corrupted state, though data clearing signs you out.
Does WebView matter?+
Updating Android System WebView can fix crashes in apps that use it.
Would safe mode help find the cause?+
Restarting in safe mode disables third-party apps for a moment. If the crash stops, another app may be interfering.
Could low storage matter on Android?+
Yes. When storage is nearly full, apps can crash while saving data. Free space by removing unused apps and large files, then restart the phone.
