Hello Артур! Thank you for reaching out. I am Tin, an independent advisor, and glad to assist you today with this issue. The issue your having might be caused by accidentally deleting a file. Here is what you can do.
*Check the Recycle Bin, look for task.vds and restore it if it's there.
*Use a File Recovery software, like Recuva EaseUS, Data Recovery Wizard or PhotoRec.
*Check for backups, if you use OneDrive, File History, or backup software, you might be able to restore the file from there.
