This happens a lot. Most likely the rope broke last time you closed the pool. Then when you opened it the ropes came out of the pulleys and got tangled, Or if it broke while you were using it the tension snapped it back.
This can be a simple fix. If you are handy and have some patience.
You will want to get 2 new ropes since they shrink and expand after use so using an old and new one can cause problems in keeping the leading edge straight.
If you decide to get 2 ropes and do it yourself let me know and I can give you some steps to run the ropes. If you have someone do it then it shouldn't take them more than 2 hours to run 2 new ropes.
From what I can see in your pictures it looks like the rest of the system should be in good shape.
If you have to close the pool you can remove the ropes and pull it manually then use the switch to open it.
Let me know if you need anything else.
