Many people think the first people to play your game should be strangers. That's like doing marketing in hard mode. Getting strangers to play your game is always going to be more difficult than getting people you have already formed some type of relationship with to play it.
Ask your friends and family to play it. Go to your Discord servers and talk about your game (with mod approval oc). If you have an online presence on TikTok or YouTube, talk about your game there.
Use the network you already have to find people to play the game. Those people will help you reach others outside of your network
