Hello! I'm sorry to read that, I will have a look at what I can do, I'm unable to repro the issue on my end unfortunatly so far so I will let you know when I find a fix. Sorry for the inconvenience. Have you tried reloading the page ?
I managed to connect the game but the problem has not disappeared. If you are using Addresables, you need to make some changes so that such problems do not occur.
I do not use Addresables no. I now disabled the auto load when joining the page. This might help. Which system are you running it on and which browser ? I can check if it's specific to that. Chrome works quite well, Safari aswell in case you want to try with those.
