starting blueproxility create a loop of connect/disconnect on my device

when I start blueproximity (version 1.3.3) the app load correctly, install in task bar ( I have installed snixembed from https://git.sr.ht/~steef/snixembed for some other use and it works well for the taskbar)

but then, as soon as I activate the bluetooth, there is a loop of connect/disconnect of my phone (samsung).
So I got constant notifications, every seconds, of connect, then disconnect.
This is very annoying, and it populate the screen of notifications.
Moreover, it do not list my devices in the know or discovered devices.

I have then removed my device from the knows devices, so it not connect/disconnect loop, but blueproximity still not able to discover the device. even if I put the MAC address on the "MAC address" field
If I re-associate my device with my computer Blueproximity can then discover it, but it start looping again in a connect/disconnect state.

So in that state I can not use Blueproximity.

It is not connected to the snixembed since I am having the same issue on Pop!_OS. Same loop, same troubleshoot methodology.

Also, in addition I discovered that when the loop is starting, I can manually also connect my phone to laptop and it will succeed after 1~7 retries and then the proximity will be off and screen will unlock and lock randomly.
