Geforce experience not opening

Unfortunately, the Geforce Experience website does not have an intuitive support button, so the only place I could go was here. If my message is not on topic, redirect me to the relevant topic or give me a link to it. Or just help me solve the problem without reinstalling Windows.
Thank you
A month ago I encountered the fact that the downloaded driver in geforce expirience did not want to install. I tried to switch to the lab version of geforce expirienc - the program stopped opening. I tried to run the uninstaller - it did not open. All this time the program hangs in the task manager. I deleted the files manually and tried to reinstall the program - halfway through the installation, the program itself disappears and remains only in the task manager. What could be the problem? I live in Ukraine, there were no blockages, it seems.
