Typing is interrupted

[SP53]

When I am typing in Keynote or in Pages, it interrupts typing ( both my own and my client's when they are typing on my screen). We suddenly hear a chime for each key as we type, indicating typing on the screen has stopped. Sometimes, the Zoom home screen pops up, and we have to click on the page again to make it go away and resume typing. Sometimes, it happens 10-15 times in an hour. This just started happening in 2025. Help!
