This was never happened to me before. anybody know how to fix it?
Try these things:
(a) Uncheck the "Strip Engine Code" from project settings -> other settings
(b) Try to build your project outside the current Unity project
Change the Company Name and Product Name to "ProductName". You can do this by:
Edit => Project Settings => Player
Both of the fields will be on top of the inspector.
I do not know why this is the case, but this surely fixed my issue, and hopefully yours would too!
