I'm not sure if this is the same issue, since the log @lukeea12 attached contained no crash, but Continuity crashes for me with Quilt loader 0.21.0. Running 1.19.4.

Your version of Quilted Fabric API does not contain Model Loading API v1, which Continuity uses.

This seems like a Quilt issue because the changelog on Modrinth for the QSL version you are using says that it includes Model Loading API v1 and the code in the Quilted Fabric API repository also includes it.

ok, thanks for the help anyways.

So what should I do? Report the error in their page?

I do not know what the cause of your issue is; I was replying to Arthurmeade12 and am already in contact with the QSL developers to resolve the issue. The log you sent did not contain any issues.

I will assume your issue is the same since you are also on Quilt and using Minecraft 1.19.4. It is being tracked on the Quilted Fabric API repository since it is not a Continuity issue. QuiltMC/quilted-fabric-api#138
