Traumatizing First Day in Barcelona! Need Urgent Help!!

I arrived in Barcelona on the 12th of January with my wife, and as soon as we set foot in Barcelona, we got Robbed!!

We took an AeroBus from the Barcelona Airport to the Pl. de Catalunya where we took off our luggage bags and a laptop bag from the bus and started walking towards the station entrance on the opposite side of the bus terminal to take another bus from there. We stopped right in front of the Placa de Catalunya for 2 to 3 minutes to look for directions where we could find an elevator to enter the bus station since taking the stairs with all the luggage bags we had with us was impossible.

We saw an elevator on the left side of the road where we were standing and started walking toward it.

We took the crosswalk to the opposite side of the road and when we reached on the other side, we realized that the laptop bag was not with us. We've kept it on top of our luggage bag the whole way as it was too heavy to wear on the shoulders. We returned to the front of Placa de Catalunya, where we were standing, but it was no longer there. We went to the bus terminal but the bus, which took us from the Airport, had already left and we couldn't check it.

At this point, we were traumatized, on our very first day in a foreign country, we got the biggest possible loss of our lives. The bag contained two laptops, one M3 pro and the other one was Dell i5 13th gen, our original educational documents from high school till the PhD, our PR documents, and a whole bunch of my savings in a crypto wallet (which I've been able to recover most of it, but still there is some more that are of no use to the thief without a password).

It was 9 AM, and there were just a couple of people minding their own business. We didn't see anyone taking our bag, and neither did we realize it had fallen somewhere in the way (as it was quite heavy, and we must have felt something if it was to fall on the way when we were crossing the road).

The most frustrating part was from the security officials. When we were looking for a nearby Police station, we saw a Police car and asked them to stop. After explaining the whole situation, we mentioned multiple times that there are a lot of CCTV cameras around if they would just look, maybe we have a chance to get our stuff back. But, they said we would first have to go to a Police station to file a report and then they would "investigate" it. We went to a nearby police station to file a report, they asked a whole bunch of questions and gave us a copy of the report. When we asked them how long would it take since all they have to do is check the CCTV footage and everything will be in front of them. But they said they don't know how long it's gonna take since there are hundreds of robberies every day.

This sent chills down my spine and I lost all hope that we were ever gonna see our belongings. We also asked some of the locals here about what happens in the cases of such robberies and they said "Absolutely nothing", and that we should forget about it and move on.

I'm already suffering from depression, and this event was enough to make me sit in the middle of the road and cry over my loss and the incompetence of the Police department.

Please let me know what are my options now. Are there any chances to get my stuff back? Is there a way to look at the CCTV footage ourselves, since there were 4 CCTV cameras that I saw for myself pointing in the same direction?

I don't want to lose hope since these are my life savings that were just gone in a couple of minutes. If any competent Private investigators can do this stuff before the police find some time to "investigate" it, I'm willing to pay for the services.

Thank you all in advance, and I'm looking forward to some helpful suggestions.
