Help with Price Impact please!

Hello, I’m using Uniswap in Coinbase. I’m having an issue swapping my Saitama back to to ETH. Every time I try to convert it back, I get the Price Impact Too High error. I’ve tried adjusting the slippage and can’t get anything to work. Is there anyway around this?
I know someone is gonna say something about scamcoins as a response, but I’ve made 10K off of it and I just want to take out my initial investment. My buddy has the same coin, uses uniswap in Coinbase and he can swap at anytime. Anyone know why I’m having a hiccup?
