Uninstalled 8.5.6 and updated to 8.5.7. The first project I opened worked. Then I tried to open another project with menu File etc… Appstudio asked if changes in the former project should be saved. I tried yes and no. In both cases the next project did not open. Next try was to open …project with double click. Project opened but does not show design window of Form1. Now the project will hang whatever I do. Cannot close AppStudio except by killing the application with task manager.
Log shows: ```2022-06-07 15:53:35,607 - root - ERROR - An exception has occurred!

I deleted the indicated Temp files before a new run. This did not help either.
A newer, not he latest, log is:

If this has not cleared up, it might be necessary to do a complete uninstall:

bsommer · June 7, 2022, 8:26pm

Wasted another hour, doing the complete uninstall procedure twice

ghenne · June 7, 2022, 9:03pm

Are you on Windows or MacOS?

bsommer · June 7, 2022, 9:19pm

Thank you.
PC with Windows 11.
Meanwhile I replaced the corrupted project with a backup from another Win11 device. Working fine now, after some trouble with entering all the preferences (Werkzeuge / Einstellungen) once more.

ghenne · June 8, 2022, 1:16pm

While I’m glad this has been cleared up, I’m concerned that it happened. If it happens again, or you have more information, please let me know.

bsommer · June 8, 2022, 1:53pm

Today I updated my Win11 Surface Pro 8 to 8.5.7. Everything seems to be fine.
