I try to generate a mesh around a delta wing (see attached picture). I sliced the geometry at the trailing edge (using Design Modeler as I find using SpaceClaim rather tricky) , however I'm still not able to get an inflation layer around the sharp edge as well as between the sting and wing connection. Is there anyone who could help me out please?
I have also tried to slice the geometry similar to how I would go about it in ICEM, but this approach also fails.
Thank you very much in advance for your help.

Did you try increasing the "Maximum Angle" to 180 deg? This option is available when you enable advanced inflation options. See below snapshot.

From the images, it appears that there are 2 bodies. Due to this, the inflation layers are not getting transferred from one body to other. You need to select the wing faces from both bodies on which you need to grow inflation layers. Also, make sure that you also select both bodies in Inflation settings.
I am not sure if there is any particular reason behind having 2 separate bodies. Can you try combining them into one and then try generating inflation on wing faces?

Yeah, they are one body. But I gave them the same name "wing plus sting". And I picked this for the inflation layer on named selection. The only thing I did is that I have sliced the body as I was hoping this would resolve my issue. Which it didn't.
The mesh without the slice looks like below. You can see that the sharp corners are still causing an issue for the inflation layer

The mesh looks very fine near the walls in first picture. Can you try coarsening it which will help to improve the inflation in the corners?

In Advance Inflation options (in Global Mesh settings) set "Collision Avoidance" to "Layer Compression" and "Maximum Angle" as 180 deg.

I have done this already. I get a warning that states that inflation created stairstep mesh at some locations
