They are both fine here. Sometimes there is a difference between "fast" and quick". "fast" can be related to speed; "quick" can be related to time. For example, if your boss asks for a "quick word", he wants to spend a short amount of time to talk to you. He wouldn't ask for a "fast word" because that would mean talking quickly. Notice how I used "quickly" to explain the meaning of "fast"? Yeah, that's because they usually have the same meaning. Don't worry about the difference too much.

The only difference is between fast and quickly. So I searched the two words and I found that: Fast, quick, rapid swift the four adverbs can represent people or things movement speed is quick, but slightly different meanings. Fast is The emphasizing the action, speed quickly. Quick say "fast", "agile", "flexible", time is short.To highlight the action alert, rather than the frequency of the action, such as quickly glance.

In terms of meaning, there is no difference.

Hi there! There is no difference between these two sentences, they both work absolutely fine :)
