Yes, your advice is not useful to me ... because the old wallet is working, and 1.1.1 when updated (did according to the instructions, Windows) says that the password is not correct. so I can not create a new one (it does not show a phrase, an empty window), and I can not restore a new purse by the phrase .... I already wrote in a discord. I think we should look for a mistake in the wallet, since it's not just me alone.
I have the same problem, and a week ago I wrote about this problem and I'm waiting for an answer, devs said that he will figure out what the problem is, but so far no response from them. And now I see that the problem is not just my wallet.
