@Phydam This error is usually shown when PrusaSlicer is unable to find the shader files on disk. Could you please run prusa-slicer-console.exe and check if any error is reported into the console ?

I saw the exact same message on the fist run, with 2.6.0-alpha-4, on windows 11. No 3d display. Then I tried prusa-slicer-console.exe, it ran fine Then I opened prusa-slicer.exe again, it ran fine too this time

so after running prusa-slicer-console.exe it threw a bunch of errors looking for the shaders in the 140 subdirectory of the shaders folder. checked the folder and they were not there. checked the zip file and everything looked good there so i deleted the whole folder for the alpha and extracted it again. Runs fine now.
