Is 1,355 calories too little?

Hello, I’m currently on my weight loss journey but don’t know much about nutrition and everything related to it..

I’ve been using the app to count my calories but I don’t know if it’s recommended to eat 1,355cal a day for an average of 2lbs lost a week. I’m lightly active (around 8k steps) and don’t really work out.

I think I have lost some muscles as I can’t open jars easily anymore. So I’m a tiny bit worried that this budget might be too low for right now and my body is burning fat and muscle.

I could raise the budget to 1,605 calories for 1.5lbs lost a week. Should I do that instead?

Thank you for your time!!

Extra Info: I’m vegetarian and most of my protein intake is from eggs and yea.. That’s pretty much it.
I average around 43g of protein.
