SystemUI crash on first launch — RuntimeException: Null or empty currentSystemRoutes in MediaRouter2.loadSystemRoutes

[wisevessel]

Steps to reproduce/复现步骤

Flash LineageOS 22.2 (Android 15) on Poco X3 Pro (vayu, SD860) with Magisk + Zygisk
Install/enable Vector debug 2.0 (3043) as System Framework, with Iconify 7.3.0 (foss) module enabled (any scope, even just its own app package — tested both)
Reboot device

Expected behaviour/预期行为

SystemUI should launch normally on boot without crashing.

Actual behaviour/实际行为

SystemUI crashes on its very first launch with RuntimeException: Null or empty currentSystemRoutes. Something is wrong. in MediaRouter2.loadSystemRoutes → → findOrCreateProxyInstanceForCallingUser → getInstance → RouterInfoMediaManager. → InfoMediaManager.createInstance → MediaDeviceManager.onMediaDataLoaded.

Isolation testing:

Crash occurs with Iconify scoped to system/systemui/settings.
Crash still occurs with Iconify scope reduced to only its own app package (no system scope) — same stacktrace, first launch.
With Vector completely disabled (System Framework off), the crash does NOT occur and boot is clean.

This confirms the issue originates from Vector's own framework hooks affecting MediaRouter2/IMediaRouterService, not from any specific module.
