Hi everyone, I’m using Anki on Windows 11. After launching Anki, I first got this error: “QtWebEngineProcess.exe - System Error: The code execution cannot proceed because Qt6WebEngineCore.dll was not found.” I tried reinstalling Anki, but the problem continued. I also found that Qt6WebEngineCore.…

I met the same problem,so i used claude code to help me to figure out the problem .I think this might be the true reason: Anki’s main interface is rendered by QtWebEngineProcess.exe, a Chromium-based child process spawned by QWebEngineView. On startup, this child process attempts to create a GPU-ac…

Anki used to work perfectly, now when I launch it i get this error and a blank window behind like this. I am on windows 11 25H2 with all updates installed as of 2nd june 2026.

I did a clean uninstall with those folders included and then installed the old version via the latest terminal installer you have on your website. I’ll try installing via directly downloading the old version from your link

Please try Troubleshooting Step #6, changing the video driver. (Remember to quit and restart Anki each time after you make a change to the video driver settings.)
