cleaning: how can I remove a piece of dirt from inside the lens system of a compact camera?

Background

I have a Panasonic Lumix compact camera, which, out of nowhere, caught some dirt between the lenses or the sensor.
I made sure it wasn't in The exterior of the lens.
Zooming (optically) did not change the size or position, but at best it became more or less fuzzy (but never sharp).
This is what the lower left room of a photo looked like:

I tried to expose the camera to moderate forces (shake, twist) at different target positions (i.e. optical zoom levels), but the particle did not move at all.
I did not open the camera.

Then when I tried to take another photo to demonstrate the effect, the thing disappeared as suddenly as it came.
Obviously something I did made it move, but I have no idea what.

Years later it happened again. This is the lower right corner of a photo of a white background:

Real question

My problem was luckily resolved, but I wonder what specific efforts I could have made. That is why I am asking: If a piece of land gets stuck somewhere in the optical path of a compact camera, what are the possible actions that can remove it? I'm only interested in solutions that don't involve disassembling the device.

Are these soft spots caused by dirt on the sensor?

Can anyone tell me if this is dirt on my image sensor? They appear in the same place in other images.

dust – Wondering about dirt on the sensor

Maybe. Your supplied example does not show obvious dust. You can get a "clearer" view by stopping at f22 and taking an unfocused photo of a wall without distinctive features or a clear sky. The shutter speed does not matter. Any residue on the sensor will look good. Note that debris on the surface of the rear lens may also appear, although softer …

technique – how to remove dirt / paste from a CPU

I want to photograph a CPU that had a heat sink in it. After I removed the heat sink stuck from that CPU, it left a sticky paste on it.

Can someone help me with any ideas on how to clean it?
I've already tried it with a cotton swab and 70% alcohol and it does not take off

There is dirt on my sensor

I just cleaned my sensor with a cloth and when I tried the dirt, I saw different dark spots in the image. That I have to do? I tried blowing with a blower, but it did not help.
