Hi, when trying to use an Adafruit Feather 32u4, I am getting an error that says Compilation error: Invalid FQBN: missing platform release arduino:avr referenced by board adafruit:avr:feature32u4. I have verified that the proper boards have been installed via boards manager. Thanks for any help.
If your board support package is installed, verify your FQBN is selected in your IDE.
IDE >> TOOLS >> BOARD >> AVR BOARDS >> your board
Thanks, it is selected.

You could try removing and then re-installing your board library in case it got corrupted somehow?
Hi @wcthompson. Arduino boards platforms may reference resources from other platforms. In this case, the referenced boards platform must be installed in addition to the primary platform.
The "Adafruit AVR Boards" platform of the Adafruit Feather 32u4 board references resources from the "Arduino AVR Boards" platform. The error indicates that you don't have the "Arduino AVR Boards" platform installed. If you select Tools > Board from the Arduino IDE menus, do you see "Arduino AVR Boards" listed in the "Board" menu?:
