ExcelClaro I’ve had this issue for a few months. It occurred after a standard windows and/or computer update. I didn’t take note at the time which update. I’ve only had issues with Excel no other programs.
I went through the standard options of clearing the roaming files, running XLStyles to clean the workbook, running in safe mode, updating windows, office, computer etc., uninstalling and reinstalling office, uninstalling and reinstalling office with support and recovery assistant, running the system file checker to repair files etc. None of these helped.
I noticed this error occurred when moving within a sheet or between sheets. It was not workbook dependent as it happened with different files some complex with macros, some simple without macros, some new, some old. All of those files worked without issue on different computers I also use (both cheaper laptops running windows 10 and both using 4K external monitor). It never occurred when idle, only when moving within a workbook.
In running Windows Event Viewer I discovered a Windows Hardware Error Architecture (WHEA) event with the PCI express root port every few seconds. This was caused by the Link State Power Management setting for PCI Express. Turning this off (from the default power saving mode) fixed the WHEA issue and after making this change I was trouble free for a couple of weeks. In the last two days I've had the issue again on a couple of occasions. Beforehand it was a continuous problem happening multiples time per hour.
Computer: Alienware Aurora R12, Windows 11, Office 365, 64Gb RAM, i7-11700k, Nvidia GeForce RTX3070, Samsung 4K
Id_rather_ride I have no WHEA errors. You should search for new drivers or BIOS on Dell website.
I'm testing new drivers (chipset AMD X570 + nVidia), but no luck.
Also I discovered there is an optional update KB5017380:

"Fixed an issue that occasionally causes explorer.exe to stop working when explorer.exe opens"
tomoam2 thanks for the reply. I've run all windows updates, updated all drivers etc. on the system. The WHEA errors disappeared once the Windows power setting for the PCI was changed. Today I set the display graphics for excel to high performance, no issues since but it's really just grabbing for straws at this point. Mine issue quite specific to the one machine, I've had no issues on two other laptops.
