Welcome back s2021.
First of all, I think that we need to define what is an Ayin Hara.
I know of two explanations:
1) Psychological – someone stares at you and gives you the creeps
2) Spiritual – Someone looks at you with bad intent and bad things happen. Why? because their malicious stare (and sentiments) can be like a prayer to Hashem.
I beleive that either of the above can happen.
