Hello guys,  
I have a problem with CasparCG 2.4.0 on my PC. Everything was working fine, but suddenly I still have the errors (see below). The PC is a SER8 Ryzen 8845 with AMD 780m graphics.  
No system errors, no graphics or OpenGL issues, same driver, only a Windows update (version 11 23H2) was done recently.  
I have the same problem with all versions that I run “as admin”. My test configuration is simple and works well on a Dell laptop.  
As soon as I do “PLAY 1-1 EMPTY” (or any other command, no matter with which client) the errors chain and impossible to stop the server without killing the process.  
A helping hand to help me find the problem would be appreciated. Thanks yoo very much.

It needs nvidea graphics card. If it is there already, window update may have removed the driver. The log is showing ATI card.

Not working on AMD graphics ? I just knowing it and impossible to replace video card.Everything worked well until last week. If I have to buy another PC again this year, I will stop developping on CasparCG and choose another solution ☹

Updated : I tried on a virtual machine, same thing. I formated PC and reinstall Windows 11 (version 24H2 this time) this morning : same thing, impossible to play anything on CasparCG 2.3 to 2.4.1.

I don’t understand why.

This isn’t entirely true. Other graphics cards do work, but are more likely to not work for weird reasons than nvidia cards.  
A chunk of my testing/development is done on AMD cards (on linux), but I know that there are some known bugs with certain cards/ranges that cause everything to break

OK I’ll give up and find other solutions. Thanks for the help.

Just out of curiosity: What other solution do you have in mind?

OBS or C# personal program.

I am not able to output on Decklink in C#, I have to convert in SDI from HDMI with 2 adapters. Working, but not perfect sync for fill/key.

The more valuable solution still CasparCG. But now, not working on AMD PC from last week.I tryed all drivers and reboot PC each time. Always same errors when playing content.
