Software completely broken after PC reset.

Hello,
I have a serious issue with character simulator.
I've been using this software without issues for two years now but I recently had to reset my PC, thus I also had to reinstall character animator among other adobe apps I frequently use. However unlike photoshop, Illustrator and inDesign who work perfectly fine, character animator seems to be completely broken and neither a reinstall of the software, nor a download of an older version could fix this.

Regarding the issue in question:
When I start the Programm everything seems fine, but I am unable to start a new project. clicking on "new project" or using "ctrl+alt+n" does not lead to any response and if i try to open one of the example projects that the software provides, the interface is completely messed up as seen in the screenshot (don't wonder about the way too bright camera picture, thats another issue unrelated to this).

Has anyone ever experienced this issue or any idea what could cause this?
I really need to fix this as soon as possible.

Thanks for any helpful response.
