it's got .25 btc not a lot but a lot to me . is there a default password for the default wallet?

I think it was something simple , is there a way to try to bruteforce it ? I saw something a while ago about doing this ? Like I have the dat file , can load the wallet I just can't for the life of me remember the password . The btc I sent to the wallet yesterday is the first transaction on the wallet , I never used this wallet prior but it always loads first .

I accidentally sent btc to the default_wallet in electrum for which I don't know the password or seed . I've tried every password I use and nothing , I made this wallet a long time ago and never have used it but now it has btc in it that I need out . Any help please .
