When opening Oracle Virtual VM I got the Critical Error below.
Failed to acquire the VirtualBox COM object.
The application will now terminate.

I encountered this issue when I deleted virtual machines while my solid state drive was full. I found out it was full because of the large amount of data I let timeshift take up…
After deleting some timeshift files and virtual machines and adjusting timeshift paramaters to prevent this from happening again; I found out that Oracle VM was not working. I reinstalled it and still had the same issue. I after searching online I found articles that said to reinstall and to restart the setup. I then noticed a few articles about deleting the VirtualBox folder in .config. I got to the .config by opening the terminal and typing cd .config . I then saw the VirtualBox folder and did a cd into that also. After listing the contents I saw lots of virtual machines I don’t have anymore and decided to just run a rm * on that folder to remove all the files.
I was able to open up Oracle and some files were restored that Oracle uses and now it works with no problem.
