Can confirm this on a Raspberry Pi 3 Model B (Debian 12, arm64, Wayland/labwc, pm2) after git pull && node --run install-mm to 2.38.0 (Electron 44.4.5). The server and all modules started fine, but the mirror never displayed. In a plain test BrowserWindow loading localhost:8080, the renderer crashed about 16 seconds after the page loaded. There was nothing in dmesg (no OOM or segfault), and it happened with and without --disable-gpu.
Pinning Electron 42.5.2 worked as a stopgap. I then tried 44.5.1 (npm install --no-save electron@44.5.1) as papinist suggested, and it works on my Pi 3 too, including after a reboot. So 44.5.1 looks like the fix for this crash. Thanks wimThoelke, papinist and Sam.
