version 6.4. dont work

since I installed the new version 6.4, I can’t open the program. I tried to uninstall and reinstall the latest version 6.4.2 and the result is the same - the program cannot be opened. previously I had an older version 6.3 installed and it worked flawlessly. now I tried to install the older version backwards, but this one cannot be opened anymore. I can’t imagine what the problem is, can anyone advise me?

Which operating system do you use?

windows 10 x64

You can try to reset the user profile, as described in LibreOffice user profile - The Document Foundation Wiki. On Windows it should be sufficient to move or delete %APPDATA%\libreoffice\4\user.

I SOLVED THE PROBLEM.

I had experienced the same problem that i could not open any files (i use 6.4.2 version). I tried to disable the hardware acceleration, and it works now.

Thank you so much, Jmux!
