Yes, you can use "thanks to" in this sentence. Sometimes "thanks to" has an ironic tone and sometimes it doesn't. I recommend checking some example sentences in the dictionary. 🙂

Thanks to COVID, many people lost their jobs. This is correct sentence but it is like a joke. You can use "Thanks to" like this. "Thanks to my job, I can travel to many countries" "Thanks to teacher, I could pass the exam"

It depends if necessary . Because it was disturbing for the concerts .

Thanks to used for positive outcomes. Due to is used for both positive and negative outcomes. So, no, when you are talking about job losses (which is not a positive outcome), you cannot use thanks to.

if you mean it in a sarcastic way
