Are you sure this issue was caused by Isometric Renders? Looking at the log neither it or its dependencies were loaded when the game crashed.
Looking a bit further it seems you are using JourneyMap for 1.20.4, which would be incompatible with 1.20.1

Can confirm, it looks like the error is with loading JourneyMap, and that it looks like you're using the wrong version of it for your minecraft version

now I tried download it again. In actions I found working on 1.20.5 version. But all builds for 1.20.4 are expired. What can I do, if I need 1.20.4?

You should just be able to use the existing 1.20.4 release: https://github.com/gliscowo/isometric-renders/releases/tag/0.4.7%2B1.20.3
