Unable to open a project in Windows via drag&drop, when the project is stored in a GPKG file on a mapped drive or a drive that is not C:

What is the bug or the crash?

We cannot open a QGIS project in Windows via drag&drop, when the project is stored in a GPKG file on a mapped drive. QGIS complains that the URI is invalid. Everything works fine if we open the project via QGIS Browser, or move the GPKG file to a local drive. "Open From... > Geopackage" works as well. There is even no error when we open a project from a GPKG file stored in SharePoint using WebDAV.

Steps to reproduce the issue

Store a QGIS project inside a GPKG file and put that file on a mapped drive (i.e. X:).
Then try to open the project via file drag&drop.

Versions

QGIS 3.22.3 Windows

Supported QGIS version

@jfmoyen can't confirm this, just tested on Win10 and 3.22.3

Interesting, so there would be something wrong with my file. Let me investigate, I'll come back to you. I wonder if it may be related to the OP's issue.

GEO001M_exp.zip

This, for instance, does open happily if I drag it from C:\users\me\documents but not from D:\GISData\France\BRGM\France_1_000000

No, the D-path does not contain any space or weird characters, and it is not specially long, either.

This is the actual error I get:

Please let me know if there is something else you'd like me to try.

This is the actual error I get:

@jfmoyen yes, I was too quick before, D&D from d: drive and the selecting the project saved in the GPKG will result in that error.

I can confirm that it only works from C: drive.

Is there anything we can do to get this issue solved? ... sponsoring? 🤔🙄😊

@cxcandid Sponsoring could be a solution indeed

In QGIS 3.30.3 (Windows) D&D works from D: drive as well, but not from USB and not from any mapped network drive.
If I open a network directory via UNC path in Windows Explorer, D&D works pretty well.

In QGIS 3.36.0 project opening from GPKG via drag&drop doesn't work from D: drive anymore 🙁. C: drive is ok and UNC path is supported.
