7.5.3 crashing on load song

I have a project that has been crashing on startup for quite a while. I don’t have a fix but a workaround. I first open a small project that will start up and then use file-open to open the problem project and then activate it. It works every time. I have tried saving the project after this but it still crashes on startup unless I open another project first This has started happening with another project since I installed 7.5.30. It has started up directly after saving it but it might just be an intermittent problem and maybe it crashes sometimes but not others. I have never determined just what has to be in the project that I open first but an empty project does not work and I think it has to have a VST instrument. Maybe a particular one and I just happen to have the right one.
