According to https://plugins.craftcms.com/cp-css it should be compatible with Craft 3 as well though...

Looks like you're trying to install the Craft 4 version of CP CSS (v2.5). The last Craft 3 compatible version is CP CSS v2.4.0.

Try lowering your composer requirements to ^2.4. And if that doesn't work, you can lock it in as 2.4 exactly.

"doublesecretagency/craft-cpcss": "2.4"
