The sentence is redundant, if docker desktop uses cgroupsv2 then can only run in kubernetes versions > v1.19
However, if users already know they are using cgroupsv2 , they will check this subsection independently of what they are using as container runtime 🤷

Could you please take a look on this comment #2629 (comment)

yeah, the point I'm trying to make is that the known issue should be a section Docker Desktop 4.3.0+ and inside somethink like " docker desktop uses cgroupsv2 ... , link to the release notes of docker desktop ... and only works with k>1.19 ... ink to subsection "Failure to create cluster with cgroups" ... the person that has it failing will look for docker desktop in the known issues, right?

can you add it as a subsection instead?
