Hi @Jorge Gossain Neto, Thanks for reaching out! Let's try a few things to get your Photoshop working again.
1. Resetting the selection tool: Select the Selection tool, right-click (Win) / Control-click (Mac) on the Tool Presets icon (in the Options panel) and select Reset Tool from the menu.
2. Update Photoshop: Make sure you have downloaded the latest version of Photoshop.
3. Update your drivers: Keeping your drivers up to date is important for optimizing performance.
4. Disable GPU: Consider turning off GPU acceleration under Preferences > Performance if the issue persists. If this is the case, let me know, and we can investigate further.
Please try these steps first and see if they resolve the issue. If not, let me know so that we can continue troubleshooting. I hope this helps! ^CH
