Compatibility report: 8cx Gen 3 + Windows 11 ARM64 build 26200.8875 — only v2 NoGApps works

Posting this because the existing crash issue (#710) only covers Snapdragon X Elite / build 26100, and I want to share data from a different platform (Qualcomm 8cx Gen 3, Windows 11 ARM64 26200.8875, zh-CN UI) plus which combination actually runs.

Test matrix (WSA 2407.40000.4.0, all ARM64 builds from this repo)

Build	Result
LTS_7_HOTFIX_1 NoGApps	❌ WsaClient.exe crashes ~130 s after launch, 0xc0000409
v2 GApps (with KernelSU)	❌ same crash
v2 GApps + WSA-Patched system vhdx	❌ same crash
v2 NoGApps	✅ Works

Crash signature (the failing builds)

Faulting application name: WsaClient.exe, version: 2407.40000.4.0
Faulting module name: ucrtbase.dll, version: 10.0.26100.8875
Exception code: 0xc0000409   (FAST_FAIL_INVALID_ARG — _invalid_parameter fail-fast)

Same signature as #710. The crash is related to the GApps images: on this machine any build containing Google Play services mirrors crashes, the NoGApps variant does not. This matches zoinve's note in #710 that v2 NoGApps is the only working combination.

What works on v2 NoGApps (verified)

• Install.ps1 registers the package cleanly (after fixing the packaging defects, see the packaging issue I opened).
• VM boots: vmmemWSA reaches ~2–3 GB, adb connect 127.0.0.1:58526 works with developer mode enabled.
• adb install works; native arm64-v8a apps run fine (tested: bilibili HD tablet APK — installs, launches, window renders on the desktop).
• ro.build.version.release = 13, ABI arm64-v8a.

Performance caveat

Interaction is noticeably laggy on this 8-core 8cx Gen 3 machine (15.4 GB RAM) compared to x86_64 emulators like MuMu. Running WSA and MuMu at the same time is painful — both VMs fight for CPU/RAM (vmmemWSA ~3 GB + vmmemNemu ~1.2 GB plus system overhead). If you need Google services or smooth UI, an x86_64 emulator is a better experience on 8cx Gen 3; if you just need a few arm64-native apps and no Google, v2 NoGApps is a solid free option.

Takeaways for maintainers

• The packaging defects (wrong makepri.exe filename, dropped empty apex/ dirs) block out-of-the-box installs — see the issue I filed.
• A "which build works on which platform" compatibility table in the README (or a pinned discussion) would save people a lot of trial and error.
• 0xc0000409 still happens on ARM64 + recent Windows builds even on the LTS build — worth re-stating in the release notes.
