App crashing due to IllegalAccessError

[otto-25]

Note: The following crash is happening only when the app is downloaded from play store. If I generate a debug or release build (with proguard enabled/disabled) from my Android IDE, it works fine.
Seen this crash so far in Android 9 and 10.

I have implemented the OnSignedListener in a fragment. When I start signing, the app crashes with the following stack trace:

Fatal Exception: java.lang.IllegalAccessError: Illegal class access: 'com.github.gcacace.signaturepad.views.SignaturePad' attempting to access 'com.yulu.ops.yuzenapp.newYuzen.ui.prive.customerInfoPager.customerSignature.d' (declaration of 'com.github.gcacace.signaturepad.views.SignaturePad' appears in base.apk)
