Can't reopen timelines.

I have a issue where I can't open timelines in network projects, if I close a project and reopen it then the timeline won't load, I can only open a backup of the timeline. This has never happened before, I have used network projects since the release of DaVinci Resovle 19 and had no problems with it before around a month ago. I do not understand what is happening, it might be a server hardware issue since it does work on local projects.
This is a little problem since we have 3 computers, to edit larger projects but that is a bit harder now that network projects have stopped working.
Does anyone have a fix for this?
