Windows Audio Device Graph isolation - taking up alot of memory in Zoom

8/5/2025 5pm
Zoom causes computer to go to black screen. I believe it is related to Windows Audio Device Graph isolation taking up alot of memory when Zoom - at least this is what I was able to determine a week or so ago when this last happened. I am running a brand new high performance HP laptop with 64GB memory. I had to shut the computer down and restart. But then switched to accessing the Zoom meeting on my iPhone instead of my laptop.

Zoom version 6.5.7

Zoom ran fine on my old Dell laptop w Windows 10. But Zoom entirely freezes (black screen) my new HP laptop w 64GB memory and NVIDIA GEFORCE RTX discrete graphics card. Zoom version 6.5.7. Last week when I attempted a meeting, Zoom froze but I was able to see Windows Audio Device Graph isolation taking up all memory.

NOTE THAT WHILE I was composing this message and had the Zoom app open, but not in a meeting, Windows Audio Device Graph isolation began taking up all memory. I closed the process.
