I'm actively working on the bug. Right now you can switch Dark Reader off for slack.com

https://dashboard.workos.com also crashing Might have the same underlying issue

Well, after 3 days of debugging and finding an actual line where it breaks, I conclude this is a Chrome bug. I will try some workaround...

This is unbelievable fix https://github.com/darkreader/darkreader/commit/1cc8018eefa732ba34800e177f04669d210ba8af

It doesn't fix WorkOS issue, but I suspect it's related to those new :is() and :where() selectors.
