I have a parent: F:\VirtualBox VMs\VM1\VM1.vdi. I just create a new virtual machine and managed to restore this VM by just selecting this .vdi. So parent works fine.
Then I have linked copy: F:\VirtualBox VMs\04_09_2020\Snapshots\{017a19a7-c039-4f77-8515-97aaea082263}.vdi
Every time I try to add linked copy to Virtualbox I get an error:

I tried everything I could but none of solutions worked.
Here is the proof that linked copy above belong to VM1.vdi:
