3dConnexion Driver preventing Photoshop from launching

Hey, @FlyingSaucy. Thanks for sharing the troubleshooting steps you've taken and your findings with the 3DConnexion support. Please share the system info from Photoshop Help > System info > Copy and paste into a text document > Upload and attach here.

I'll move this to discussions for now. Please ensure there are no stale preferences in your Photoshop. You can go to the location of the preference folder below and rename it to back it up. (https://adobe.ly/3u7u84j)

This method is more effective compared to the in-app Reset Preferences at quit method, and just replacing the Preferences.psp file. 

macOS: Hold down the Option key in the Finder when using the Go menu. The library will appear below the current user's home directory.

Library > Preferences > Adobe Photoshop [version] Settings

Rename the Adobe Photoshop folder by adding a .old at the end. (Adobe Photoshop 2025 > Rename > Adobe Photoshop 2025.old)

This will give a fresh start to Photoshop as a new installation. Before you launch Photoshop again, make sure Photoshop has the required permissions on the macOS: https://adobe.ly/3Jrs1jN;
