[iBotPeaches]

Since the stacktrace appears to be in userland - I'm guessing this is some anti-tamper code. You can run some tests with like

• -r - skip resources
• -s - skip sources

That'll help eliminate the possibility of disassemble/assemble causing issues.

Using - s will not cause this error, but I need to modify smali to debug. Is there a way to solve this problem

[iBotPeaches]

You can pull a bleeding edge build from the artifacts of the latest build here - https://github.com/iBotPeaches/Apktool/actions/runs/8048426591

This has an internal upgrade to smali/baksmali. I would try that. If no, I fear this is internal detection of modification and thus probably out of scope of something Apktool can automatically fix.

[iBotPeaches]

I'm closing after testing myself this appears to be anti-tamper behavior. Apktool can't do much about that.
