Taking screenshots in Big Sur causes system to hang
On a 2018 Macbook Pro, running Big Sur v11.1
When using CMD-SHIFT-4 to take a screenshot and save to my desktop (which I frequently do), the preview of the screenshot will be displayed in the lower right corner of the screen, and then it hangs there for an extended period of time (30-60 seconds). Hovering over this preview displays the spinning wheel indicating that something is causing the system to hang. Eventually the screenshot will appear on my desktop as it is supposed to. Opening that screenshot and attempting to use Markup on it will also occasionally cause the system to hang for a similar period of time.
I've had this MacBook for some time now, and prior to Big Sur, never encountered this issue (and I take a lot of screenshots for my job).
Any advice on clearing up this issue would be appreciated.
