Premiere Elements 2021.1 Memory Leak with nVidia GPU and Intel integrated graphics.

[defaulta47izyqsf4mn]

I am running Premiere Elements 2021.1 (Version 19.0, 20210127.daily.2235820) on Windows 10 Pro 20H2, build 19042.804).  After using it for less than 1/2 hour, the memory usage maxes out (16GB) and the SSD usage goes to 100%.  The screen goes black and comes back, but no longer using the nVidia GTX970 GPU, but rather the Intel integrated HD Graphics 3000 on the i7 2600k.

I have disabled the Intel graphics device in the task manager, but the problem persists.  The nVidia GPU is using driver 461.72.

Since I have only been using this a day on this particular machine, I cannot say what all triggers this, but so far it was a file save requester and narration.  Any suggestions for how to fix this?

You MAY need to go into BIOS at startup to disable the Intel

That appears to have done the trick.
