Premiere 2020 Not Responding Halfway Through an Edit

[User143458723]

Hi,

My Adobe Premiere on the most recent update has suddnely become non responsive. I was halfway through an edit, about 10 minutes long with almost no effects added into it yet and it froze on me entirely. I restarted my pc after waiting 10 minuts to get a save done hoping that would fix the issue. I then opened it all up again, cloed everything else on my computer, and tried again. Same thing happens, completely freezes program and goes unresponsive. 

PC SPECS:

i7-9700k

16gb 2667 RAM (13gb allocated to premiere in preferences tab)

2080 SUPER (Enabled in settings)

500+ GB HDD Available

Any help would be appreciated, this is a very important project that I would hate to lose progress on so any sort of uninstalling of apps etc scares me so hopefully there will be another workaround. Thanks in advance!

EDIT: Lag specifically ONLY occurs and freezes when nested video sequences are visible
