Description:
What software is involved?:
Operating System: Windows 11
Cryptomator: 1.17.1.5803
LibreOffice: 25.8.1.1

Volume Type:
WebDAV

Relevant Log Output:
In event viewer, I see messages like:

1) The program soffice.bin version 25.8.1.1 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Security and Maintenance control panel.

2) The description for Event ID 14901 from source WebClient cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

Anything else?
This wasn't an issue when I last tried maybe a few months ago (cant remember when exactly). This is the first time I tried in a while and first time it hasn't worked. I mostly use cryptomator for libreoffice document files. Please help!

Steps to Reproduce:
1.Unlock drive on cryptomator
2.Navigate to a .txt, .odt, .ods document
3.Open the document using LibreOffice
4.Close the document (pressing the X at top right)
5.Document immediately hangs and needs to be forced closed
6.Saving also seems to cause crashes and the changes to the document before the crash are not saved
7.If I open a .txt file in notepad it seems to function normally
8.cryptomator's volume type is set to: automatic

Actual Results:
Closing the document crashes. Saving the document crashes. Saves are not saved and are lost.

Expected Results:
Close normally without crashing. Saving normally without crashing and actually saving your changes.


Reproducible: Always


User Profile Reset: Yes

Additional Info:
I also created a issue github ticket and they suggested it's a LibreOffice issue and to create a ticket here. Here, you may find some relevant info: https://github.com/cryptomator/cryptomator/issues/3996

Issue was reproduced by others.

relevant information from my github link is:

"You did not mention you were using WebDAV as volume type. I tested this shortly and can reproduce it. Interestingly, LibreOffice also asks for non encrypted-webdav shares for a password. I think the issue is here at LibreOffice."
