and simplify stopped . i had look to this error prone class but not understand why it giving error because all tool can parse it as proper .smali file . lost original apk , only this apk left because in this i merged 2 dex into single one as simplify not aware about multidex yet

on Android tool i see error shown as Instruction format Format45cc not supported which seems similer to https://github.com/JesusFreke/smali/issues/767

This is a smali / dexlib2 issue. You can work around by rewriting the smali / deleting problematic classes. I'll update to the new dexlib version when it becomes available which should be v2.5.3 or higher.

apkunpacker commented 2 years ago

yeah sure . till then closing issue , will try to remove problematic classes

CalebFenton commented 2 years ago

I'll leave it open to remind me to update dexlib versions. ;)
