PollyMC has been taken over by an insane alt-right contributer that kicked out other contrubiyors and takem over the project. Use Prism Launcher instead which is made by thr kicked out contributors. https://prismlauncher.org/
Prism needs a microsoft acc to work afaik, there probably is a fork that doesnt but i dont know of. All my recommendations came from either the megathread here or fmhy.net
