Virtual BOx won’t open any of the machines

Hello guys, I hope you are all doing well. I am an ethical hacker by profession and currently am doing reverse engineering IDAPython. However my virtual machines got messed up, I have tried all means it’s ain’t working:
Below are are the approaches I used but didn’t solve the problem.
-Enabling Hyper-V from the command prompt
-Enabling Virtualization in the BIOS setup but all this didn’t work.

Any help is highly appropriated.

Is it the same thing ? Virtual machines won’t open on the virtual box
