My GPU GTX 1050Ti not working with ae FX 2017 after enabling cuda

Nothing wrong more or less. Ti cards have always been problematic since they use customized shader engines optimized for games, not professional apps, limiting their compatibility. Unless you can find a way in the nVidia control panel to enhace compatibility by e.g. manually disabling specific features or setting them to more compatible values, this may never work. in any case, there is no "Which button must I press?" answer here. You realyl need to spend time experimenting with these options and figuring out which one works on your system.
