When trying to import a deck in the deck collection the app immediatly return an error message saying "Deck import failed with the following message : The input string contains an invalide line: my password"

I use mtg arena on both android and windows. The issue was first discovered on windows. I've been able to import decks before, the account is pretty old (3year at least I would say but hadn't been used for months and I started playing again 3 days ago)

On android the error message is "Deck import failed with the following message:The input string is empty." (Same account)

The password has been change several times for similar ones so there's chance the password displayed in the error is not my current password but a previous one but in any case passwords shouldn't be stored in clear and should be hashed.

I'm sure it's one of my present or former password as I don't use this in any other field in any application.

Never had big issues before, only some minor connexion problem.

While writing this I reconnect in the window version which now display "Deck import failed with the following message : The input string contains an invalide line: will trying to import deck". I had already try to reload the app before reporting the bug but it was still displaying my password.

I would like to have a feedback and explanation about it (and to be able to import deck)

The two attached screenshot come from the windows version and has been taken between 12pm10 and 12pm20, french time on the 15th of may 2026

Update (12pm36 french time): after changing my password, reloading the game and reconnecting the message came back to "Deck import failed with the following message : The input string contains an invalide line: my password" with my new password. And the app ketp displaying new errors if I re-try.
