My PS4 keeps crashing, what can I do?

Today while gaming, my PS4 (approx. 1 1/2 years old) suddenly simply went out and could not be started. It only started again after I pulled the plug and waited for a while. Unfortunately, it keeps falling after about 15 minutes. Tried several times throughout the day, but always the same. It goes for a short time and then crashes. When I turn it on I always get the message that I would not have turned it off properly.

Could it be because too much dust has accumulated inside and is therefore overheating? How does it keep crashing? Already tried from the outside with a handheld vacuum cleaner and blow to remove the dust. I also encountered some dust. In the end it did nothing.

Open it and clean it up.

Gives enough YT videos how to do it.
