I have seen a few threads of people saying that their apps remain minimized in Windows 10. There are responses recommending updating of video drivers (always a good idea) and even one about re-installing Windows 10. I don't know if this will work for everyone, but I had a similar problem and here is what I did, which worked for me.

I use a dual-screen configuration and it was set to 'Extend'. To resolve my problem I took the following steps:

1. Selected Win+P which opened the options for extending my screen to multiple monitors
2. I selected 'PC screen only' which led to only my primary monitor showing the screen

At this point, I was able to open my apps without problem. I selected Win+P again and extended the display. I checked and the apps could all still open without problem. Ultimately this may be a driver issue, but short-term this fixed things for me.
