When i tried to click the "attach" button on jjsploit when roblox is open it does nothing

When i have roblox not open and click on the "attach" button it says your normal thing "JJSploit did not find Roblox. Make sure a game is opened! A game must have been launched from the Roblox website. The Windows Store version is not supported" you know about that right? But then when i have roblox open and click "attach" button, it does nothing.

Edit: When i keep jjsploit running for 1 to 2 minutes it says "Could not find DLL! Please reopen JJSploit and wait a few seconds for it to redownload. Disable your anti-virus if its deleting the dll"
