This is most probably due to the preload bundle (Component-preload.js or library-preload.js) being generated into string which has to be eval'd at runtime. To avoid that, exclude the third party library from the bundle. See my other answer at Solved: HowTo use 3rd party lib with content-security-policy omitting eval()" - SAP Community.

If the issue still occurs even after excluding the third party lib from the bundle, follow my other Q&A How to Fix "String as JavaScript" Errors in FLP? (Async Module Loading) - Stack Overflow where I have summarized documented best practices for CSP compliance.
