In my project, I'm running into conflicting version suffixes error for cats libraries. I ran sbt evicted, but I could not fully make sense of how to interpret it to resolve this error. Here is the evicted output:

EDIT: duplicate of Akka HTTP SBT modules were resolved with conflicting cross-version suffixes in ProjectRrf
On top of what Mateusz explained, the error message is saying that you have some dependencies (cats-kernel and cats-core) pulled both in their Scala 2 and Scala 3 "variants", i.e. cats-core_2.13 and cats-core_3 are pulled (where the suffix is the Scala version).
This is forbidden.
This can happen when pulling multiple dependencies transitively and/or when using the SBT for3Use2.13/for2.13Use3 option (doesn't look like you're using it in this case).
For instance, maybe you're pulling explicitly Cats Scala 3 but you're pulling dependency X in its Scala 2.13 variant (you can, it's compatible with Scala 3) that itself pulls Cats for Scala 2.13.
In this case you should look to exclude one of the two Cats, most probably the 2.13 one.
