Getting Refused to execute inline event in jquery-3.3.1.min.js

[Nasirul Akbar Khan]

Getting the following error in jquery-3.3.1.min.js,

Refused to execute inline event handler because it violates the following Content Security Policy directive: "script-src 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-...'), or a nonce ('nonce-...') is required to enable inline execution. Note that hashes do not apply to event handlers, style attributes and javascript: navigations unless the 'unsafe-hashes' keyword is present.

I'm also using jquery.dd.js before using that it was fine. I've checked both the files found nothing suspicious. 

I've attached the two files with this. 

Please kindly help me out. Noting is working...
