VMplayer closes on start of vm

I want to install ubuntu as a virtual machine on my ubuntu machine. The version of the host system is: Ubuntu 18.04.4 LTS The iso I want to install is: ubuntu-18.04.4-desktop-amd64.iso So I downloaded vmplayer and ran:

sudo bash VMware-Player-15.5.1-15018445.x86_64.bundle

When I run vmplayer in terminal, I get

[AppLoader] Use shipped Linux kernel AIO access library.
An up-to-date "libaio" or "libaio1" package from your system is preferred.

(vmplayer:19995): Gtk-WARNING **: 19:11:09.896: Inserting action group 'WindowActions' into UI manager which already has a group with this name

I select "Create new virtual machine", fill everything out, choose /home/me/vmware/Ubuntu 64-bit as location. I choose 10GB disk capacity and "Store virtual disk as a single file".

there is more output on the terminal:

Unknown file type (unallocated) /home/t/vmware/Ubuntu 64-bit/boot/.. - ignoring and continuing.

Now when I start the machine("power on"), the window closes and the terminal says (always from 1 to 5):

Solution 1:

Enabling hardware virtualization in BIOS solved the problem for me.
