Error: Class "Drupal\config_ignore\Plugin\ConfigFilter\IgnoreFilter" not found

config_split_ignore requires config_ignore version 2.
In order to support version3, the project must be recreated from scratch.

Then I just have to leave 8.x-2.4 version of this module?

Are there any plans to do so @maximpodorov - as config_ignore 2.x seems to be unsupported now?

I've created a patch for the config_ignore module that improves the out of the box experience and ensures that without any surprising configuration requirements the configs are ignored when expected , even if they're split.

Patch #3 worked for me.

Related issue #9 did not work for me in this bug by it's self when running drush commands.

Both patches do work together.

My environment:
D10.2
config_ignore: 3.2
config_filter: 2.6
config_split_ignore: 1.10
