The only way to find and solve the problem yourself is to disassemble the camera and test all the details that could cause a breakdown.

The problem may be in the ripped mount, in the contact group of the shutter actuator or gear. I had a similar situation to Nikon 5100, the mirror stuck at the top point, after the first frame, and without manual editing, it did not fall into place, and then the problem repeated. Sometimes there are problems out of the ordinary, so it’s easier to give a fix to a professional. This happened to me after the camera fell.

It can happen if dust or debris gets in the mechanics.
On a well used body it can be even down to the normal abresion over the years.
I only had an Olympus but I noticed that after long exposures in the 10-15 minute range the shutter would sometimes get stuck and ruin the image.
The big problem is the image sensor behind it.
You just don't want anything to end up on it and you can really wipe it either.
I found two options to deal with debris in a shutter mechanism.

First is to use DRY ICE that is finely crushed and to place it onto accessible parts of the shutter mechanics.
In my case the culprit was the frame holding the shutter blinds.
When the ice melts the released Nitrogen flushes out tiny particles.
Activating the shutter a few times helps to get tiny ice crystals and the gas moving through.
The temperature shock helps with stuck particles.
Once the shutter moves again keep it open and inspect the sensor with a magnifying glass.
There should be nothing sitting on it.

Extreme case of being really stuck due to debris in the mechanics:
Use a suitable container you can seal of and add a thin air hose to - preferable just a small soda drink bottle and a latex hose.
Get a thick injection needle from your prefered supplier as well.
Drill a hole in the bottle cap that is a bit less in diameter than your latex hose - means you won't have to add a seal ;)
Check if all is sealed by blowing in the hose while holding the bottle under water - there should be no bubbles coming...
If so then add the needle to the end of the hose - leave the protective cover on for now...
Prepare a pot with hot water and fill some dry ice into the bottle, screw the hose cap on and shortly after you should get a nice gas stream out of the needle end.
If the ice acts too slow then put the bottle in the water until you get the more pressure but don't leave it there as the pressure might go up quickly!
If too highe the hose will pop out or the needle pops off - so make sure you secure the needle properly!
Use the needle to direct the gas stream into the mechanical parts.
Don't be shy to use multiple needles you bend to get where you need to go.
The cold stream of gas can blow quite a lot of stuff out that the previous option can't.
But you need to be careful as you don't won't blow things apart.
The benefit is that there won't be any residue and far less condensation compared to using these spray bottles with compressed air.
Plus you can use it to remove possible debris from the sensor.

No dry ice available?
As a last resort these bottles with compressed air to clean sensitve computer parts can be used.
Do not use anything with liquids or added solvents as you never know how it might react with the black coating.
Alcohol usually leaves white marks here...

IMHO the best option before risking a headache is to have it checked by a licensed dealer or photography shop.
If debris is the cause they can quickly clean it and if lubrication is required then they have the right lube and tools fo it.
As part of a full service it is usually well worth asking ;)
