I build airgap-vault from source code myself(following the README), after installation, it gets stuck on the logo screen.
I’m sure this is not the Android System WebView issue, because I tried multiple newer android system webview versions (142.0.7444.173,138.0.7204.181, 139.0.7258.158), and also different cellphones(sony, xiaomi).
