This may be a temporary tool, assuming Oculus fix the issue. But in the mean time...
Do you have multiple right touch controllers appearing in the device list that can't be removed using the remove option?
These fake controllers are caused by faulty entries in the DeviceCache.json file.
Oculus Phantom Touch Remover is a little tool that scans the DeviceCache.json file and removes any entries that look bad (mainly a Type of "controller", SubType of "rlcon" or "llcon" and Tracking Type of "unknown").
This only works when the Oculus Service (OVRService) isn't running (it only reads the file on start).
Other devices won't be affected, you won't need to run setup again (unlike if you just delete the cache file).
To use:
Use the Windows Task Manager (service tab) to stop the OVRService.
