Trojan on Hydra Launcher?

Hi! Today I decided to download the PRAGMATA repack from FitGirl through what seemed like an official source. Everything was fine before. But this time, Microsoft Defender flagged something called Kepavll!rfn. Is this a normal situation or not? This is the first time I've encountered something like this.

For reference, here's the source: https://hydralinks.cloud/sources/fitgirl.json
