Delete the library folder and attempt to restart, that’s a good general-case fix before reinstalling Unity.

The crash happend in the third party library “libcef.dll” which is part of the Chromium Embedded Framework. That means you use some sort of third party native libraries which might be out of date or you used them in a wrong way. For example the Steam client uses CEF as browser.

You told us nothing about your project so we can tell you nothing how to fix it.

sorry guys but the problem is the unity keeps crashing on loading screen. that’s the problem…
i have no problem in other except that.
