Hi All, many thanks for taking time to read this.
Firstly, the system, Wins 10 (all updated), Graphics drivers all updated, Photoshop also updated. Notebook is Dell Vostro 5471. GPU have been disabled in Photoshop.
Photoshop simply failed to launch, but have discovered a work around.
From the device manager, I see that there are two graphic cards. Intel(R) UHD Graphics 620 and Radeon (TM) 530, the workaround is to disable one of the graphic card, then PS will launch normally.
If anyone can shed some lights on this would be more than greatly appreciated.
Best regards,
PT.
