I'm trying to make a modpack, got this error when starting the game:

java.lang.RuntimeException: Failed to read accessWidener file from mod connectiblechains at net.fabricmc.loader.impl.FabricLoaderImpl.loadAccessWideners(FabricLoaderImpl.java:480) at net.fabricmc.loader.impl.launch.knot.Knot.init(Knot.java:145) at net.fabricmc.loader.impl.launch.knot.Knot.launch(Knot.java:71) at net.fabricmc.loader.impl.launch.knot.KnotClient.main(KnotClient.java:23) Caused by: net.fabricmc.accesswidener.AccessWidenerFormatException: line 1: Namespace (named) does not match current runtime namespace (intermediary) at net.fabricmc.accesswidener.AccessWidenerReader.error(AccessWidenerReader.java:281) at net.fabricmc.accesswidener.AccessWidenerReader.read(AccessWidenerReader.java:90) at net.fabricmc.loader.impl.FabricLoaderImpl.loadAccessWideners(FabricLoaderImpl.java:478) ... 3 more

Mods:

Console additionally says this:

Oooh i see better clouds, anyway. Access wideners did not change in 2.0.0 and it seems like the jar was not compiled correctly as the version is $(version) (instead of the actual version).

Did you download the mod from modrinth because I just noticed that a wrong file was the default?

Yes!

Download it again, I've selected the correct file. @legoatoom it was connectiblechains-2.0.0-sources-dev.jar

If it works, please confirm so I can close the issue

it's working just fine, thank you very much!
