Thanks for sharing your opinion. I’ve made some more search, and it look more like a Oomycota. I’ll move it there.

If so

I do not believe it is anything in the Clavicipitaceae, Cordycipitaceae, Ophiocordycipitaceae, etc., as there is no evidence of perithecia, asci, or really anything distinctly fungal.

It come from the inside of the larva

On the first picture, we can see that it is extruding from the head of the larva. It cannot be a saprophyte fungus as it would be around the larva. Anyway, I’ve noticed them only on fungus gnat larvae and many other arthropods were present in my sample.

what makes you suspect this is an entomopathogenic fungus?
