Steps to reproduce the problem:
There is no way to consistently reproduce that problem but basicly I played with the device and it started sending weird values in the event listener, values that were completly wrong, one event listener kept firing while the others stopped working and then the problem started.

What is the expected behavior?
The promise should resolve or reject and not freeze and if I'm running a line of code not making the browser stop responding and crash.

What went wrong?
The connect promise never resolves causing it to freeze and when I try to run the code again even before I get a chance to choose the device from the chooser the browser stops responding and then I have to crash it.

Not exactly sure, maybe has something to do with this issue - https://webbluetoothcg.github.io/web-bluetooth/#issue-f363405f.

Did this work before? N/A 

Does this work in other browsers? N/A

Every time i tried to connect to the device i failed and made the browser crash (only that device btw).

After a couple of hours and enldess amount of crashes, I restarted my computer and I successfully managed to connect to it on the first try.
