[Branched] Al editar fotos en Lightroom no se abren en Photoshop

Unfortunately you don't have wrote anything about your system and the installed software. 

So my answer is just a guess.

If you have installed Photoshop Beta 25.0 it's a known issue.

P: Lightroom Classic>Edit in PS: Long Delay+Errone... - Adobe Support Community - 13966962

You  can rollback to Beta version 24.7

I've heard about this issue also about systems there's no Beta installed.

In this case try this: Use the Adobe Creative Cloud Application to uninstall Photoshop. When asked, keep preferences! After this reinstall Photoshop again.

If this doesn't help the nest step is to reinstall both apps Lightroom and Photoshop. Please follow the steps below:

1. Open the Adobe Creative Cloud Desktop Client and uninstall both Photoshop and Lightroom Classic. When asked, keep preferences! 

2. Install Photoshop first and then Lightroom Classic. The right order is very important here!

If this doesn't help try the reinstallation with removing the preferences also.

If this also doesn't help try to rollback to Photoshop 24.6
