Sessions not generating Qr Codes...

[TitoBahe]

Some sessions are not generating the Qr code properly. The session is stopped, no phone number is conncted to it and it still cant generate the QrCode. I dont receive any Error logs. Only this:

INFO (SessionManager/1): session:MlgLW6t9H3C4G9wRD6RI-clientId2 - Starting session... {"reqId":24644,"session":"MlgLW6t9H3C4G9wRD6RI-clientId2"}
INFO (SessionManager/1): session:MlgLW6t9H3C4G9wRD6RI-clientId2 - Session is already running. {"reqId":24644,"session":"MlgLW6t9H3C4G9wRD6RI-clientId2"}
INFO (1): request completed {"reqId":24704,"req":{"id":24704,"method":"GET","url":"/api/sessions/MlgLW6t9H3C4G9wRD6RI-clientId2","query":{},"params":{"0":"api/sessions/MlgLW6t9H3C4G9wRD6RI-clientId2"}},"res":{"statusCode":200},"responseTime":1}

It says the session is already running... I dont get it.
And btw this session was created right after other successful sessions:

Session 1 -> generates Qr Code 🟢

Session 2 -> genarates Qr Code 🟢

Session 3 -> Bugs

Session 4 -> generates Qr Codes 🟢

Session 5 -> generates Qr Codes 🟢

All of those sessions were created one after another in a for loop.
It started happening after assining proxies (I am using proxy6 )to the session and it has happened pretty frequently, does it have any correlation?

Here some more logs:

OBSSS:

After restarting the session a fair amount of times on the WAHA' dashboard, the sessions becomes "Failed" and starts generating the QR Code again.
Why does it happen?
