Yeah I'm having the same problem too, but it's even worse for me as it resets at 25%.
I'm trying to install it on a steam deck, you? Now it restarts at 47%. Not sure who's end the problem is on yet but I'm thinking it's not ours. I've come across other launchers with the same issue before and the devs fixed it on their end. With most of those games though, there was an alternative way to install the game.
