Check engine light and compression loss

The vehicle first turned on the engine fault lamp on a rainy day and said, “engine failure; Have the vehicle repaired”. There was a tremor when I started the engine; but when it got hot, I didn't have any problems starting the car. When I took it in for service the spark plugs were changed. The problem did not recur for a month and a half. But I don't know if it's a coincidence, one evening while I was driving, the same fault lamp came on again. The vehicle did not get gas while the lamp was flashing. When you pull to the right and turn it off and on, the malfunction lamp became stable, the vehicle took gas and returned to normal. Then, the flashing event repeated a few more times on the road, and we threw ourselves to the authorized service in Adana by turning it on and off. It turned out to be "ignition error". They said no problem, temporary breakdown and continue with peace of mind. But the next day we had the same problem again on the road.

The authorized service that changed the spark plugs in Istanbul called this evening, there is no problem, but there is a compression loss in the engine. If they repeat, they said that the engine may need to be replaced, it may cost like 100 thousand TL.

Can there be a compression loss in a 2020 model 45k km vehicle, I can't quite understand what the problem is. The option to replace the engine makes no sense. If there is something that will require engine replacement, the service sends you why it is okay for now; Is everything inconsistent? What could be the reason for such a problem, what could be the solution, I am waiting for your help and opinion.
