We're sorry about the trouble due to the graphics card not working in Photoshop 2021. Would you mind sharing the exact version of Photoshop you're using? Did this issue start after updating Photoshop to the latest version?
Please ensure you have the latest Windows updates installed on the computer along with the latest Quadro drivers for the P2000 graphics card you're using. Also, re-installing the graphics card drivers from scratch may help.
