All my windows open at the same time every day

MacBook Pro 16-inch, 2003 Apple M2 Pro Sequoia 15.3 Every day at 12:05pm (the time isn't relevant, but it's always at that time), my MacBook Pro opens every window from all my open apps and stacks the windows on one desktop (I have an external monitor). These are windows that I have minimized into the dock/app icon, but they get opened and moved to a single desktop. I have no idea what setting does this or why it happens. Any ideas? Thanks!
