That is completely normal. For example, I lose about 0.5-1kg of weight after a week of not training, and I look pretty flat. That will mostly be water tho.
After two weeks without training and while eating a shit (but oh so tasty) diet and drinking wine everyday for one of those two weeks, I lost about 20% of strength on the main lifts. And it felt way worse than that. But it’s just a temporary loss, and I was back up after a couple of weeks.
My unsolicited advice is to not worry about it and just start from what you end up being capable of after a break. It probably is not your first, and it definitely won’t be your last because life happens.
