Incomprehensible entry of the host machine when starting vagrant, where to look?

Question

virtual box

Something strange is happening, I can't find the logs.
Prehistory: there was a project, everything worked well, rearranged the main (host) system (it was necessary to replace the screw), returned the project to the machine from git, raised the VM, everything worked well. Then I turned off the PC and did not pause the VM (I did this before and there were no problems). The next day I try to do vagrant up, but I got a PC freeze. I hit my head against the wall, nothing happened, I decided to reinstall vagrant, deleted the old machine and tried to roll vagrant again, again I got a PC freeze, but I didn’t get a normal VM start from the first time.
1) I try vagrant up, the startup process starts and when the virtual machine starts, the computer freezes completely.
2) I tried to manually start the VM from the virtual box (GUI), the situation is similar
~/VirtualBox\ VMs/VMname/Logs - 2 files, but empty
/var/logs/ didn't find anything interesting either...
where else can I look? What happens when you start a virtual machine?
UPD
When executing the vagrant up --debug command, I got a PC freeze:

Maybe something will become clearer?

Answer 1

I don’t know what the problem is specifically with you, and it’s unlikely that my answer will somehow help, but I’ll write it just in case. I also had a problem with the computer freezing. I looked into the system monitor, and it turned out that after exiting the virtual machine, the VirtualBox process remained in my memory and it occupied 500+ MB of RAM. Finished it and everything was ok.
