Thanks for reporting, we will have a look at this tomorrow.

Do the examples included in the plugin work correctly?

I just tried to reproduce your issue by uncompressing the b5 zip, opened the Samples project, and created a "New Studio Project" in the root of the Unreal's project. But I can create new pages, edit them and everything seems to work just fine.

Could you explain what you did different or provide a sample project that reproduces the issue?

Hello,
I don't want to throw you on a wrong path but I had a similar issue and I had made a project on C:/dev/MyUnrealProject and I had this issue. I assumed that maybe, because it was on a work computer that I may not have all the write access for it so I moved the whole project to the same path but on my D: drive (D:/dev/MyUnrealProject) and it was working. I don't really know if that may be the cause?

Another thing could be that. It also was a project that was created on another computer on my D:/dev/ root path and was cloned on a C:/dev root path so it could be that some path aren't absolute or rely on the drive to be the same.

I have reproduced and fixed this issue for the next release.

It was caused by Unreal's FPaths::GetProjectDir() returning a relative path under some circumstances, which was not being handled correctly.

Thank you for the reports.

I have created a ticket for an issue that seems somehow related (maybe I am wrong) : https://www.noesisengine.com/bugs/view.php?id=4548
But instead of not being able to open files, it doesn't find Noesis Studio resource that should exist like font style or icons whereas if I take the same plugin folder in another project, it works fine (so it seems very project dependent)

Thank you for the report. I have asked for some feedback in the ticket, as I have been unable to reproduce your issue.
