Arc GIS Pro freezes when clicking 'browse' button in various places

[XiaomingLi]

I'm working with ArcGIS Pro 2.8 and 2.9 well on Win10 with a license from my university.
But yesterday when I launched it, I found a weird problem, that when I click anywhere with the 'browse/folder' button (to locate some files or folders on my PC), the interface of ArcGIS Pro will freeze. But if I type a file/folder path, it works well. Pressing 'Esc' will unfreeze the interface, but if I click 'browse' button it will freeze again.

I suspect it is a problem related to my operating system. But I have no clue by now.

Here are some instances:

1. creating a new project.

2. connect to a folder.

3. export a feature class.

I just started using ARCGIS Pro this week, and I have been having the same problem - every time I click the browse/folder button, the program crashes - not just freezing like in the main thread. Any thoughts? I really can't even begin to learn to use the program with this issue.
