I recently updated my dependencies, including updating androidx.appCompat from 1.2.0 to 1.3.0. It took some digging to figure out that this is what was causing my crash.
The crash doesn't occur until the user clicks on a MaterialCardView to transition to a new fragment on the home page.
Removing the dependency update resolved my issue. Does anyone know what in androidx.appcompat:appcompat:1.3.0 might be causing this? Here's the crash log:
