I have some good news and some bad news. The good news is your Bryce is in impeccable order. The bad news is something has gone horribly wrong with your extensions. I can see that under Type it is identifying the correct file types so it is not getting confused about it and knows what they are. I noticed the IrfanView PNG's look to be having the same issue.

Just another thought are you using Windows 10? I can't remember now but wasn't 3D Builder an included app that come with the OS? and did you remove it from the Program Files or the Command Prompt? I am pondering whether the removal has taken some core files with it or sent them south. There is no reason why 3D builder would interfere with Bryce and as I have pointed out the icon that appears on a file is just a prefered option to open remote from File Explorer and can be changed to suit Bryce or any other software. Importing from inside any software that handles the files does not care which software brand icon is showing

One option will be to reinstall this program and see if that helps unless the issue you are having with the OBJ's existed before you removed the 3D Builder

Now here is how mine looks and we both got the same file from here
