Yes, crashes seems again to be caused by this file : lawnchair/src/app/lawnchair/ui/preferences/data/liveinfo/model/LiveInformation.kt With "features" variables ..

[wlrmarl]

The LiveInformation class expects a non-null features field during deserialization, but the incoming data lacks this field. This crashes the app when parsing older data formats or incomplete responses.

Kotlinx Serialization requires fields marked as non-optional (no default value) to be present in the input data. The features and announcements fields were missing defaults, causing deserialization failures.

To Fix the Issue we need to assign a default field to features, from the code I saw at this file:-

lawnchair/src/app/lawnchair/ui/preferences/data/liveinfo/model/LiveInformation.kt.

The companion object has the empty field but by default kotlin doesnt use companion object it uses contructor one so the fix is to assign default values i think announcement should also have default value too.

So fix is (Also simplyfing how companion object is generated)

@Serializable
data class LiveInformation(
    private val version: Int = 2,
    val announcements: List<Announcement> = emptyList(),                // Default empty list
    val features: Map<String, String?> = emptyMap(),                    // Default empty map
) {
    companion object {
        val default = LiveInformation()                                                // Simplified
    }
}

This is the Fix.

Thanks

Download fixed debug apk from CI/CD Pipeline githubs action workflow here:- https://github.com/LawnchairLauncher/lawnchair/actions/runs/13920148445

[Wierius799]

Ty! Tested the debug apk and it's working perfectly now, let's hope this gets implemented soon :D

Just to keep records, 2095 crashes on launch too. 🫡

The build 2095 keep crashing on Pixel 7a when update from build 2078.

One clean install resolves the problem.
