Website X5 crashing on startup due to cefsharp.browsersubprocess.exe 
Auteur : Alan N.My version of Website X5 frequently crashes on startup.with the Event viewer shing CefSharp.BrowserSubprocess.exe is the cause together with KERNELBASE.dll. Restarting the Windows 11 laptop sometimes resolves the problem only for it to return next time I want to use Website X5. I have the crash dump files but they are 5.6MB. Anyone esle experiecned tis or have a fix please.
Many thanks
Alan

Hello Allen,
Often this is due to a problem witj windoes Visual C++: and .net frameworks
reinstall visual C++ or repair, there are tools from microsoft (search google)
for instance:
https://www.microsoft.com/en-us/download/details.aspx?id=30135
After repair try x5 again, you coulld also try to do a new install of x5 (download form your portal) in top pulldown next to your name. Your project stay save. But a backup from x5 from time to time never hurts (step5)
Hope this helps,
