Today when I started 22.2.0 (I have been on vacation for a week), it does not show anything graphic - only the top menus. (Not even the button bar.) I upgraded to 22.2.3, with no change.
However, 22.1 still works.
Have you tried reloading the default workspace? If that doesn't help, try (with FlexSim closed) deleting the prefs.t file in %APPDATA%/Roaming/Flexsim/FlexSim22.2
These suggestions and several others are contained in our article Graphics Compatibility - Common Problems and Solutions - FlexSim Community.
One suggestion that always seems to clear up issues is to update your graphics driver to the latest version from the graphics vendor (AMD, Intel, Nvidia). Don't trust that Windows Update or your PC manufacturer (Dell, Lenovo, etc.) are giving you the latest driver. That is almost never the case. Try the latest driver directly from the GPU manufacturer.
Deleting the .t file fixed it.
The one for 22.2 was 0 bytes while the others seemed to be 3 - 6.
