You are confusing Gemini Exchange with Genesis. Gemini Exchange for now is fine, but their earn product which actually works with Genesis (separate entity) is where withdrawals were paused because Genesis is having a liquidity crunch as a result of the fallout of FTX.

Genesis was the middle man for majority of earn products for various other crypto companies so if it goes under, which it may, this week, the fallout will continue to increase in scale as a result.
