Man, I'm glad you made this post, it clears up some things I was lacking.
Last week brave/chrome had an update that 'broke' keychain.
It wasn't really broke, just actions were blocked by error messages.
With enough attempts the transactions would go through.

What I suggested you do is change your recovery account.
Not do a recovery, that is something else.
You have steem set as your recovery partner, they are not gonna help you.

You can change the account in the peakd permissions and authorities tab.
It does require your owner key.
You should choose someone that you can communicate with outside of hive to ensure that they know it is you, and not the thief that got your keys.
Or, you can set it to an alt account that doesn't store its keys anywhere near where your main keys are stored.
This to insure that both don't get stolen at the same time.

Here is arcange's service, I recommend it, if it suits you.
Or, you can use me, we just need to make contact outside of hive.
https://app.element.io/?updated=1.12.1#/room/#hivediscord:matrix.org
Matrix allows encrypted chat, so we can pass keys there, if need be.

You can see from the pic that no keys have been changed, so your account is safe.
You updated something on the account, maybe a background or something, in dec '24.
But, at the bottom is the issue.
steem won't help you recover your account.
Best practices say to change that to someone that will.
