A few things of note.....
1) In your DxDiag file it shows a bunch if issues with windows update failure and MPtelemetry(which is supposed to be microsoft windows defender related by my research). I would see about getting your OS to check the latest updates and see if you can't get it to fix and or finish your latest updates. Either roll back the last updates and redo, or see if their is an option to just repair it.
2) You may also try a clean boot, this will basically only boot up a limited pool of programs and see if you are having a program cross interference...https://support.microsoft.com/en-us/help/929135/how-to-perform-a-clean-boot-in-windows
3) I noticed you have a Wacom product installed, possibly one of their tablets?? Try removing that item and related programs.
4) You may also run a file checker on windows to make sure your OP system hasn't gotten bugged....https://support.microsoft.com/en-us/help/929833/use-the-system-file-checker-tool-to-repair-missing-or-corrupted-system
As far as the install location, at one time it hated to be in anything other than stock location, so you may want to delete/remove origin and reinstall it into stock location which is C:\program files(x86), just to make sure, then go back and make sure the install locations are rechanged back to your D: drive.. And honestly at this point, I would definitely delete the downloaded files of DA;I and reinstall them once you get Origin back into stock location.
