Hello, that’s completely normal, Roblox can’t support two different accounts on the same browser. Maybe if you switch to private browsing and then back to normal mode, but I don’t think Roblox will support it. The Roblox Player plays on your first account. However, you can install Roblox from the Windows Store and you’ll be able to play both on the website and through the Roblox app from your Windows Store. There is still a solution with the beta version, which is different from Roblox Player.
I don’t use 2 accounts at the same time in one browser, I log out of my account and log into another, but I can’t enter games, but I don’t play in the app because I need to join VIP servers using links, which can’t be done in the app
Check the privacy settings under the section “Who can follow me in the game” and “Who can invite me to a game”. Make sure the settings are configured to allow your alt account to join games. If needed, adjust the privacy settings to allow your alt account to join games.
You can’t do anything, there’s no point in resetting your PC, the result will be the same. Try checking that no program is preventing your Roblox from working properly. Check for updates through Windows Update, as they may not be up to date and therefore preventing Roblox from functioning. If the issue persists, I recommend waiting for an available Roblox update. If it still doesn’t work, I suggest consulting a Roblox technician to fix the error. It seems that the version of Roblox is not working properly with your computer, which sometimes happens. Also try right-clicking on your Roblox Player file, opening its location, and clicking on “troubleshoot compatibility issues” to test and let me know the result.
troubleshoot compatibility issues said just nothing (or no any helpul information), BUT I fixed error with my main account launching the RobloxPlayerLauncher in versions of roblox, but the main problem is still here: I can’t join any game on other accounts. Also I dont think this is a roblox update issue, I have this problem for more then 2 weeks, also my windows version is the last
