Having issues with random green glitches when adding video to timeline

[defaultcv4a0vwzqusn]

Does anyone have any ideas on what could be causing this issue to happen? I'm using Premiere Pro CC 2021 and I just got a brand new computer. When I playback an imported video on the timeline, it has random green glitches. This issue didn't occur on my previous machine.

Do not count on Windows to be fully up to date when it comes to device drivers
Go to the vendor site to be sure you have an updated driver for your graphic adapter
•nVidia Driver Downloads http://www.nvidia.com/Download/index.aspx?lang=en-us
••for Premiere Pro and MAYBE Premiere Elements use the STUDIO driver, not the GAMING driver
•••such as (MAY not be the latest) https://www.nvidia.com/en-us/drivers/results/170344/
•ATI Driver https://www.amd.com/en/support
There are also intermittent reports that the newest driver is not always the best driver due to driver bugs or compatibility issues, so you MAY need to try an earlier driver version

I have an Intel Iris XE graphics card and it says my driver version is currently 27.20.100.8783
