Did you happen to try the solution that James linked here: https://forums.autodesk.com/t5/support/fusion-360-drawings-cannot-launch/m-p/7072157#M2053
Unfortunately this Error Dialog is somewhat generic, it basically is a catch all Dialog for Fusion Drawings is unable to launch, it might be unable to launch for several reasons. In the past this issue was fixed by some of the steps listed in this thread. However these old steps will not fix the new cause for the appearance of this dialog.
Their is a chance that the steps you were attempting might have no effect, especially if the steps were linked before May 2017. The new solution/workaround if you are hitting this dialog after the most recent Update, is to Launch the program as an Administrator one time and open or create a drawing once as admin. Subsequent launches after this first admin launch will not require you to run as admin and you should be able to make Drawings just fine.
- Close Fusion 360
- Right-click the desktop icon
- Select Run as Administrator
- Launch Drawings
