Your address is bech32 so the pretense that it was "sent to different network" doesn't make sense.
That address type is native only in Bitcoin, not used or compatible in any other networks.
I think OP is just a troll or he is asking fake questions like many members this days.
I asked him to post address or transaction ID so we can know more how to help him, but he just ignored my question and wrote some new nonsense.
Seems like he is talking on behalf of someone who asked to help him out. He looks intelligent enough to understand many elements in the case so i don't expect him to be someone who is holding his savings in someone else account.
From another side, i doubt why he first told that he lost all his savings and ignore requests to provide transaction info.
Indeed, i can't see the reason why should anybody posting nonsenses.
