App crashes while scanning

[Quantum-Future]

It starts scanning, founds 5 devices and then crashes.
I attached screen captures with the errors:

The panel shows 2 interfaces:

I'm connected to wlan0. This WLAN has no internet access.
Also cell data connection is Off.
The other interface (tun0 - 10.6.6./32) don't know what it is, but if I select it and try to scan, the app crashes immediatly.
The phone is a Xiaomi with Android 9.

I also tested it on a Samsung Galaxy A31 with Android 12 with the same result: crashes after finding 5 devices.
On this phone, the left panel shows 3 interfaces:

Sometimes appears tun0 and tun1 and others appears as tun0 and tun2 (with exactly the same IP).
Trying to scan any of the "tun", crashes immediatly.
