today i had changed a cell into a value field, after refresh the table inside the powerapps designer,
the designer at windows 10 disappeared..
happened 2 times today, i had luck that there was a tempory save state.
Sorry to hear that you had a bad experience.
Could you please share some of the information on the Event Viewer, in particular:
In teh Tree view, Go to "Application and Services Logs" -> Microsoft -> Windows-> AppHost -> Admin
You may see some entry there that has information on th exception that happened.
Are you now still experiencing this issue on your side? I haven’t seen a similar issue so far.
If convenience, could you show me more details about the steps?
