FWIW late yesterday I ran the Office Quick Repair: Control Panel...Programs and Features...right-click on O365...Change...select Quick Repair. I haven't had the same issue since but I haven't been using Word much today.

>>Over the last 3 weeks or so I've been getting crashes in Word and Outlook:
>>- with multiple Word docs open
>>- while scrolling with the mouse wheel through a Word document or e-mail which has embedded images such as screen snips - as soon as the scrolling hits the image(s)
>>- (I think) Usually while working in a secondary Windows desktop
>>
>>Before it crashes completely, multiple docs get mashed together and window controls are mangled (see attached image).

>>Win10 21H2, latest patches, up-to-date Office 365.
>>
>>Anyone else seeing anything like that?
