[Solved] Please Reselect the board from the dropdown

I started to work on a sketch today and when I tried to download it to my Sparkfun Redboard it keeps coming up with "Please reselect the board from the dropdown menu" error. I've reset my Acer chromebook running Version 60.0.3112.114 (Official Build) (64-bit). I've tried plugging and unplugging the board. It always shows up as Board at /dev/ttyUSB0. My sketch compiles fine. I'm out of ideas

Thanks

I'm still having the same problem after a reboot.

They found another issue and it looks like it will be fixed tomorrow.

Bug fix is online, please let us know if this still happens.

It's still happening after a Cache clear and restart

What if you reselect the port and then upload?

Sorry I only cleared 12 hours of cache. Once I cleared a week of cache it worked
