I was able to recover the file using Resolve. In media -tab, choose the clip -> right click -> Clip Attributes -> Data Levels -> Change from Auto to Full. Voila!
Before I figured this out, I made a massive investment (over 4€ )on eoshd recovery lut, which didn't recover anything in my Ninja V files from X-T3.
