All camera manufacturers keep changing their RAW formats.
The Canon 80D requires a minimum camera raw version 9.5
Unfortunately, PSE 13 will not support that version.
Your options are to either upgrade to a newer version of PSE or use the free Adobe DNG converter. The DNG converts the Canon raw file to the Adobe raw format which you can then edit with PSE 13. See following for mor information.
Thank you. That makes sense.
