Hello! Very sorry for this issue. To compensate for the time lost, I gave you a Pro subscription that will work for 2 months, for free.
Would you be ok to send to the GDevelop team the project you were working on? We will be able to debug what went wrong. You can send it to hello@gdevelop.io with your username so we can dig into this.
Thanks for reporting this problem and I hope you will be able to continue working on it soon once we have fixed the issue!
EDIT: also confirm me your username on your GDevelop account so I ensure the pro subscription was properly given. Thanks!
