Is my plant dying after repotting?

Hi all, I’m brand new to any sort of gardening so desperately need advice! I was gifted 3 little plants that just grew in water. One of which was a monstera. I wasn’t expecting it to do much, but as it continued to grow and look healthier and healthier I figured I’d pot it up and see how far it’ll go. After putting it in soil it started to go downhill fast. The leaves are quickly yellowing and I don’t know what to do! It’s only been watered twice as I potted it quite recently. Any advice would be very much appreciated as I want my little guy to grow! Thank you!

(Please ignore the actual cheese.. it was a joke I sent to someone when they told me it was called a cheese plant and I have no other photos for reference! I had to include the photo to show how healthy it looked when it was in the water!)
