  • You should really try to produce a minimal working example (MWE), otherwise, nobody could help you... Just as a blind guess, you managed to put into your file an Arabic Kasra somewhere... if you really need it (for example in a bibliography entry) I think that you need to switch to a full unicode engine like lualatex or xelatex.

    As mentioned, please provide a full (but minimal) example that gives this error. You say you write in English, but you may by accident have pasted in some arabic character.

In your log:

l.278 ِ
        According to these variables, the target force $\bm{f}_{target}(s_q)...

You have an Arabic Kasra symbol just before the uppercase A in line 278.

Remove it...
