UiPath file icon became blank

A while ago, UiPath Studio often kept freezing, so I uninstalled it and reinstalled it.
Now, the xaml file icon has been the blank one, instead of the blue icon with “Ui” in it.


Why is it like this? When I double-click on this Main.xaml, it opens UiPath Studio. I don’t like this blank file icon.

Also, UiPath studio often freezes now. When I try to End Process from Task Manager, it becomes “Suspended” and it takes a lot of time for UiPath studio to close.
What could be the cause of this? Uninstalling and reinstalling UiPath Studio didn’t solve this issue.

Each file is very small. Even a blank project freezes when I try to do something on it.
When I right click on the left pane (Project Pane), it almost always freezes.
