Cura doesn't start after update to 4.9.1

[kruegge 0]

Hi Everyone!

 

I have updated to V 4.9.1 and ever since Cura doesn't start anymore. Even the older version doesn't.

 

it goes through all the splash screen motions and then comes up with the programm window but it stays white and after a second or so it quits without further notice.

I have found only one thread in the search but that one had issues with a drive X being mapped incorrectly. I don't have a drive X

 

I have uninstalled the old version and deleted the Appdata/Cura folder numerous times. I have also uninstalled the new version, rebooted and reinstalled but still no success..

 

I have looked at the error log but unfortunately I don't understand where the fault may be. 

 

I hope some of you guys find the time to point me into a few directions where to look for information.

 

I am running Windows 10 Pro, 21H1 Build 19043.1023 on an old Lenovo Thinkpad X201.

 

regards

Krügge

From the log you provided, it looks like something is going wrong using a "shader". This is a bit of code that runs on your graphics card (GPU). Since older versions that worked before aren't working anymore either, I think a GPU driver update is causing your issues. Try finding a newer or older graphics driver for your laptop.
