Technical Failure to remain running at start attempt 0.9 TA

[Evsahibi]

First of all, I just found this forum. I'd like to say a warm hello to everyone. I bought a used Panda. 2016 model. 0.9 TwinAir engine. Dualogic automatic transmission. Since I bought it, it mostly won't start on the first try in the morning. The rest of the time it works normally. So far, one private mechanic and two authorized service centers have inspected the car. There are no error codes. The car has 77,000 km on it. The spark plugs have been replaced. The oil and filters are all original parts. All checks, including the fuel line, etc., have been performed. No fault was found. The battery was recently replaced. The service center's explanation is that since these engines operate on oil pressure, they can sometimes behave this way. But it happens too frequently. As a solution, should I try the following:
Battery replacement
Negative battery cable replacement
Intercooler hose replacement
Fuel pump replacement

From what I've seen on the forum, there are people who bought a brand-new car and experienced the same problem. Has anyone found a solution?
