VBox 6.0.10: Windows guest freezes after opening shared folder -> duplicate of 18766

[husnikadam]

Hello, I've encountered a problem. Guest OSes can't open a shared folder with one specific file. After opening a shared folder with the file, guest OS freezes and it's not possible to use it, power off and start restarts the OS and it runs fine again... till the folder is being opened again. Different guest win OSes: win 10 64x, win 8 64x, 32bit version OS not confirmed yet. Problem happens just sometimes, but only with this specific file (file group, same problem for same files of different file versions). Once the shared folder can't be opened in a snapshot, neither host restart, guest restart nor shared folder readding helps. The only unknown circumstance is what else makes the guest being frozen or not. This problem happened many times, few times in absolutely clean guest OS. All OSes are windows of different versions, all have latest updates. Attaching screenshot of win 8.1 64x, trying to open the shared folder with the problematic file. Check the scroll bar, while the folder says it's empty, small proof of that this folder state is temporary and transitional.

I'm ready to provide the problematic file (it's our company's our own web browser installer) and Vbox log, but I can't see any tiles where to add them yet.
