Lot of application vanished from app list in my project after the upgrade to 9.13.011 meanwhile app folder are still in C:\Program Files\NetMake\v9-php81\wwwroot\scriptcase\app\projecture…
Check if those application are available to the user
Option → Settings → Users → Edit users
I do not see any application only project 
Sorry I meant Project, I thought you didn’t have access to the project itself
Look like your DB is corrupted
If you are using the SC version control under project / version control
Make sure you are on the right version.
The upgrade switches you to V1 and you have to select the latest version before you continue dev.
I use indeed the versionning to take all back.
I upgrade the version, then delete it and it restored the app…
