Crash crash

I’ve rebuilt my old 8.5 32bit with jbridge for an old track to be loaded. All works though it’s freezing irregularly, meaning I’d have to reboot to continue working.
Unsure where to start as this is a giant project.
Can anyone here help on reading crash dumps as I could upload here to try and work out what the issue is?
Thank you

Forgot to mention that when it freezes I’m able to eventually get into saving by clicking file then awaiting for the list to eventually appear, then I can click on save as which again eventually appears. Something is bugging everything…
