Local Webobjects not loading

Hi,

I have a fairly complex project with many web objects. These do not load when I export the project if the web object has not been added since the last export. So if I add a web object and then export it everything is fine, if I export it again it won't load. Instead, a directory structure is displayed. (see attached image)

I am using the current version of Articulate 360 on a Windows 11 system. My files are in a reasonably banal folder structure on Onedrive. I suspected the latter to be the problem, but a test directly under C:/ with a web object directly there and one from Onedrive does not cause any problems.

Is this perhaps a caching problem on the part of Storyline or am I doing something wrong?

Thanks in advance for any advice.
