Is it possible to restore data deleted by Adobe Creative Cloud?
If the data is worth $120 to you, DiskWarrior may help, depending on how long ago you lost data and how much use you've had on the system prior to noticing it (more use = more chance something was overwritten and is now unrecoverable). I realize you asked for no "from backup source" answers, but if Time Machine is enabled, you should have local backups stored on the computer drive, even if you don't have access to your normal backup destination. No external program necessary, just restore the folder.
