bridge launches photoshop automatically: it's annoying!

Hello everyone

When I'm on the central "content" window with my thumbnails, just clicking a thumbnail immediately launches Photoshop.

Can not click on the thumbnail to see its meta or preview.

In fact I can do it but by clicking and leaving the mouse button pressed, I wait one or two seconds and I release.

There Photoshop does not launch and the behavior is "normal".

I am working on MacBook Pro 2015 with Sierra 10.12.6

I am on the 2019 version of Bridge, I did not specify.

I specify that this behavior was identical with the previous version of Bridge.

Do you have an idea to solve this problem?

Thank you
