This behavior really sounds like something is interfering with the VPS sensor, making the drone constantly believing that something is closer than 0,5m below it... & by that tries to ascend away from it.
The constant descent following a longer descent stick command indicate the same... the...
The reason for this mishap was very likely the table surface...
This from page 18 in the user manual.
Just in the end of the landing the log shows that the VPS height disappears just before the drone tumbles over the edge of the table... this indicate that the VPS sensor no more could assist...
I usually have these 4 categories checked on that map... these areas together with the restrictions from the "Drönarkartan" makes it hard to fly in the most interesting areas on Gotland... usually I don't bother to bring a drone there.
And in these times with the war in Ukraine & Sweden...

You don't need to have the CPL on the drone when figuring out the setting... just look through the filter directly when you pointing it in the same direction as you later will take the shoot, there adjust it until you have the strength you desire.
Nothing in the log shows that conclusively... but that would have been a likely scenario if there hadn't been a FC failure.
When the errors comes in the DAT log the VPS sensor still reads 1m to what's under the AC (the AC is there directed in the same way as the roof slopes down (meaning longer...
The log doesn't contain the root cause for the FC failure unfortunately... but this was not battery or phone related at all.
Well... you actually had a 20% constant negative throttle input going from when you had positioned the drone above the nook until the motors shut off... look at the blue...
All motors shut off 191,7sec into the flight... but a accidental CSC command wasn't the reason.
According to the DAT log event stream it most probably was a FC failure... likely not a permanent, instead a computational error (as the AC flew normal after the event).
This is from the event...
... and if a uniform motion blur isn't a major concern & if a manually locked shutter speed feels too limited in changing exposure environments when videoing... you can use a auto shutter+ND as the ND filter slow down the shutter in general, not only when you set it manually to 1/120sec or 1/60sec.
If your drone model have a native DJI waypoint mode it should be possible with below Litchi utility...
