I got this error in Crashlytics, can somebody explain what this is about? I have never seen this before targeting android 31.
Fatal Exception: java.lang.VerifyError: Verifier rejected class com.rfo.german.main$ResumableSub_startbilling: void com.rfo.german.main$ResumableSub_startbilling.resume(anywheresoftware.b4a.BA, java.lang.Object[]) failed to verify: void com.rfo.german.main$ResumableSub_startbilling.resume(anywheresoftware.b4a.BA, java.lang.Object[]): [0x2C] register v7 has type Precise Reference: java.lang.String but expected Boolean (declaration of 'com.rfo.german.main$ResumableSub_startbilling' appears in /data/app/com.rfo.german-1/base.apk:classes2.dex)
The crash happened on a Galaxy Note10+ 5G, android 7.1.2
