Except I'm on windows 10.
When I open pop it says "Pop did not start properly on your last attempt. Would you like to report this issue?"
When I click start pop (or report the issue) it starts loading and says "Something might be wrong keep waiting or contact us"
If I keep waiting it says "There seems to be a problem, trying again in x seconds"
After a few of these retries it completely fails.
First I tried closing and reopening pop.
Then I tried rebooting my computer.
Then I tried uninstalling and reinstalling pop from a fresh download.
I've been using pop successfully on this computer for at least a week and a half without issue.
