I've already tried reinstalling (without keeping any settings) and deleting all preferences, nothing helped. Trying to fix the symptoms (for example 3rd party plugins crashing with errors 48::46 and 25::3) doesn't lead to anything either. These problems only occur on my AE CC 2017 installation, my AE CC 2015.3 installation on the same machine works just fine (especially with the plugins and "broken" media files). I haven't found any solutions online. I am running a Windows 10 (Build 14393.953) machine. Quick help is appreciated, I need CC 2017 for work.
Update your graphics drivers and configure them suitably.
