Hi, I suspect this is related to our new feature @LazyClassKey introduced in 2.51, which is used by @HiltViewModel. It might be similar issue to #4309, there is something changed in AGP that resulted in our obfuscation rule fails to function properly. To understand the real cause, there is a map of original class name to the obfuscated class name generated under app/build/ouputs/mapping, which can help you translate the stack trace. Please attach the non-obfuscated stack trace or a repro to help me further debug the issue, thanks!

I've encountered the same issue.
Hilt 2.51.1, AGP 8.2.2.

Adding the proguard rule mentioned in #4309 fixes the problem.

[wanyingd1996]

Fyi, a potential fix is in #4331 , it will come with the next release.
