Infinite Loading in Transaction

I was testing my wallet following all steps, but on “Transfering assets” i had a problem :

Aproving transaction is very slow but it works, BUT the next step “Sending transaction” (cf 1rst screen) is an infinite loading and after like 5m of loading, it is cancelled for “Window closed by inactivity after 5 minutes” (cf 2nd screen).

I retried many times and the same problem is happening :confused:
