I was able to recreate the same issue by following the steps. Basically in the makefile the TARGET is set to CY8CPROTO-063-BLE and when you deselect the kit in the library manager references to the kit files are removed. Thus, the Reading project information step is failing as it is trying to find the CY8CPROTO-063-BLE as the active target but it is only able to find CY8CPROTO-062-4343W and CY8CKIT-062-BLE.
As a workaround you can change the TARGET in the makefile to one of the kits that is selected and then open Library Manager. This reads the project information again, sets the Active BSP in the Active BSP field and Library Manager opens as expected. Can you please try this out and let me know if this works for you?
Libs for CY8CKIT-062-BLE are NOT in Libs directory.
When I followed the steps the CY8CKIT-062-BLE folder was created in the libs folder as shown -
Can you please confirm this?

Thank you again.
Reassigning the TARGET to an existing loaded BSP in the MakeFile did work to fix the issue.
