"Couldn’t set association for project. Check if file is writable." Error when transferring project to new desktop.

I’m getting this message when trying to open a 5.2 project after transferring the files to a new desktop. I’ve tried merging with a 5.3 project and the issue then becomes missing content. In the application, the folders are there, but no content, while in the source file all the .uasset files seem to be there.
I’ve transferred this project to other desktops and haven’t run into any issues. Does anyone have an idea on how to troubleshoot this?
