Game crashes due to Quilted Fabric API

Hi, I wanted to try out quilt for the first time, but it keeps crashing when I open it. When I first came across the crash, I had a few client side mods enabled. Right now though, I only have the Quilted Fabric API installed, and it still wont open because (and i quote) “Something went very wrong while loading mods. Please report this error to the quilt-loader project so this can be fixed.”

Here’s the entire crash report just in case (I don’t know if I was supposed to just paste it in or not, but I did anyway):

---- end of report ----

A bunch of other threads with the same exact crash report were solved by updating the Quilt Loader to 0.19.2, so you could try that.
