Low on Memory?! Cant save!

Still getting this in 2024. On a 32Gb RAM machine. I Save-as constantly, but eventually it fails and I lose work and have to restart. Very disappointing. I contacted support who said "Don't leave the application open too long" (!) They suggested I copy all the slides to a new project, which was a lot of work, and did not help. I assume it's some kind of memory-leak bug but hard to isolate. Anyone got any theories? Seems that if I tear off the timeline window and put on my 2nd monitor, I get the issue soon after? Any other ideas? I'm on a corporate locked-down PC so all the suggestions of registry hacks and patches are not an option, but likewise, I'm sure it's not a virus. The 64-bit Storyline beta looks interesting but not available to me. I can't even get the latest main release!
