windows 10 guest crashes when exploring host shared folder

[captain cranium]

I have shared a folder from my linux host and boot a windows 10 pro (64-bit originally installed from M$ download site) guest vm to use windows explorer to view the files in the share which appears as Z: drive. I choose to change the sort column to view by modified date and I can no longer get a response from the win 10 guest. The next moment I see the vm rebooting. I can reproduce this behaviour each time. Linux 64 bit vbox 6.0.10 r132072 (Qt5.9.5) I have attached the logfile

Does this happen with latest Virtualbox versions 6.0.14 and/or 6.1?

I had exactly the same problem on VirtualBox 6.1.14 since yesterday. Therefore I upgraded to 6.1.16 r140961, but I can still reproduce it and very consistently crash my Windows 10 on Linux (Ubuntu 18.04/5.4.0-52-generic #57~18.04.1-Ubuntu SMP Thu Oct 15 14:04:49 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux).

Somehow this problem disappeared and now reappeared. I upgraded to 6.1.18 (and also upgraded the guest additions), and it is again reproducabel. On th moment I click on the folder I shared, it halts the machine with following logs:

It is not all folders, but only the Download folder on my home drive and not the Documents folder for example. Following is the listing:

drwxr-xr-x  6 XXXX YYYY     4096 jan 13 19:20 Documents
drwxrwxr-x 31 XXXX YYYY   131072 feb 11 17:37 Downloads

When I move my Downloads to Downloads-old and creat a new Downloads as follows:

drwxr-xr-x  6 bdobbels bdobbels     4096 jan 13 19:20 Documents
drwxrwxr-x  2 bdobbels bdobbels     4096 feb 11 18:12 Downloads
drwxrwxr-x 31 bdobbels bdobbels   131072 feb 11 17:37 Downloads-old

I can again access the new Downloads folder without problems. If I access the old one, I get a crash, so it has definitely something to do with the state of the Folder on the host system or its content, maybe a character in a file or too large? It probably happens when the folder contents.

Any pointers are welcome.

Hi Captain cranium, I solved this issue. It was a not permitted char in file's name. In my case it was "$" created by the host (Mac OS) after moving file in the shared folder. I hope that can help you.

Cheers.
