Can you test to remove "HTC Vive cosmos controller support" from the list and after that try to add it again ?
I saw that if you had added this profile on older unity version (like 2020.3.5 where there were no problems to put it), then the profile stay in list even after update your projet to 2020.3.11.
But for us the profile can't be added on a new clean projet 2020.3.11.
To resolve that we have modified HtcViveCosmosInputFeature.cs (see my other post).
