VM not responding to neither mouse and keyboard after login

[PeterLanguila]

Hi forum, first post, so please indicate me if I did something wrong.

I have been using Oracle VM VirtualBox for years with an Ubuntu version. Today, after some months without using it I booted it and the screen sizing was small, looking like I had to install again Guest Additions.
I followed some Stackoverflow posts which indicated me to update any package:

Code: Select all

sudo apt-get update

and so on, and after turning off and on the VirtualBox it now does not work for me anymore:

I can boot my VM and I can enter the password of the only user, but after that the desktop appears like normal but freezes and it does not respond to any clicks nor keyboard interactions. In fact, the VM is working because I tried playing around again with the Guest Additions and there is the Pop up to execute that appears, but yet I cannot click on it nor select it with keyboard.

I have been trying for some hours any fix from every relatively close post around here, but nothing been working.
My objective is to recover the VM, if not possible I will probably try to create another VM and point to the same file system to recover the important files, but recovering it is a priority.

Thanks so much for any help.
