Update on this post, I went out and upgraded my desktop to the unit mentioned above and I am still have the same issue with LO crashing. I had someone from tech support remote into my computer for an hour but he couldn't find the issue. I am working on projects that have been 4-5 years in the making so the model has gone through a number of SU upgrades. I did an experiment and created a new SU 2025 file and copied the base model over from the old file and created a new LO file and the problem seems to be solved (touch wood). I can now use the new graphics engine without LO or SU crashing. Along with this I changed my file location from OneDrive, which was slow and laggy, back to Dropbox. I know not ideal to have these files in the cloud but DB seems to work way better than OneDrive. So, SU2025 cant like older SU files, or at least that is what I am finding.
