Hey @SaWu
Can you try a few things here?
1. You have confirmed that you have checked the environments, can you go to the solutions and check if the flow exists there?
2. Can you try creating a new flow and use the flow management trigger to trigger the flow (if you are an admin this will really be able to get all the flows as admin) and you can check if you find the flow there.
3. If you have shared the flow with some team members, you can check the team flows tab to see if the flow is over there.
Hope this helps!
