i bought a token from uniswap on base but when i try to swap back to eth, it says the swap failed.

i thought it was because of the token allowance so have revoked a few times and even reset my MetaMask completely.

i tried to send the tokens to another MetaMask walllet but no price/next button allows me to send.

i also tried another wallet to buy and swap the token and it worked fine so it seems to be some issue with the first wallet i mentioned.

anyone have any idea how to resolve this? i need to swap the token back to eth asap

thanks
