Zoom camera stops working during Meeting

I am using a ThinkBook 14 G6 IRL. During my Zoom meetings, everything runs smoothly at first. However, after having back-to-back long meetings—around 3 or 4—the Zoom camera stops working. When I check the built-in camera app on my laptop, it operates normally. Sometimes, restarting my laptop temporarily resolves the issue, but other times it doesn’t. I’ve found that running Windows Update can also help, but after a few days, the same problem reoccurs, and the camera stops functioning during my meetings. How can I permanently resolve this issue?
