This application failed to start because it could not find or load the Qt platform plugin

Hi all. I do not know English well, so this text was written using Google Translate. I'm sorry.
I have a problem with virtualbox 6.1.30. There was an unplanned power outage, after which the VirtualBoxVM process does not start. Everything worked before.
VBoxSDL --startvm vm starts normally.
Running the guest OS in the background starts fine.
My problem is similar to "virtualbox Ticket #17425", but without specifying a specific library in QT _debug. I'm new and can't add links yet. I'm sorry again

I tried all the tips that were described in the post at the link, but nothing helped. Please help me how can I fix it?

Running ldd didn't show missing dependencies in libraries

My host OS is Astra Linux (Debian 9 based)
