My Launcher is not opening

Experiencing the same issue myself.

According to your log, you are running launcher version 2.1.5964.

I would guess there is something wrong with some files on disk, they are corrupted or incomplete somehow. Try renaming or removing your .minecraft folder in your appdata folder (enter "ctrl + r" and then "%APPDATA%"). We will also look into if this might be caused by the launcher somehow.

I did it.

Are you saying that it works or that you have already tried what was suggested?

Still the same problem. I deleted the file but it didn't fix.

I've discovered something new about the problem. When I move the cursor on the gray screen to location of normally text, the cursor changes.

I cannot take a screenshot because the screen capture application does not show the cursor.

Cursor is "The I-beam pointer (

)"  in some parts of the launcher.

It seems the application is unable to create a gl surface (if what you provided above is actually the cef log). Please provide the complete launcher_cef_log.txt as well.
Things to try: make sure your graphics drivers are up to date or if you recently upgraded, that might be the reason you are suddenly seeing this, then please downgrade to the working driver version.
Let us know if this helped you or not.

Where is the launcher_cef_log.txt? I couldnt find it.

And I trying to update my graphic card driver.

I updated my graphics card driver and problem solved. Thanks for your help.
