EXTREMELY slow scenarios suddenly?

Hey everyone, I have a scenario that processes customer support tickets (hundreds every hour) and usually it takes 1 sec to process each ticket, and currently it’s taking 45 sec to 15 mins for each ticket!

We can’t figure out what is causing this, as nothing as changed and the server status of all tools is operational/normal.

Any ideas?? HELP! It’s causing major issues with our clients.

Please share screenshots of the process.
Also share the simple log screenshot when it was working fine and another of the simple log when the problem happened please.
