Here my friend: Found a solution after trying everything:

I figured out a solution. I simply used the Coinomi wallet, which supports Dogecoin. It has a sweep paper wallet function which I used to move the coins from the problem address into Coinomi, then I used Coinomi to move the coins.
I don't know why this sub says to use old, difficult, obscure, tools like coinb.in or unmaintained wallets that basically don't sync anymore like the core wallet when modern easy functioning wallets like Coinomi exist.
