I looked up the error log and below is the error posted:

00:15:56.193096 emR3Debug: rc=VERR_MAP_FAILED

The file was too heavy to attached to the post.

Thanks

Zipped log files always fit.

Please right-click the VM in the main Virtualbox window's VM list, choose Show Log.

Search the far left tab's log for this text:

Attempting fall back to NEM

If you find it, Hyper-V is enabled and needs to be disabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

If you don't find that text, save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.
