I'm initializing nested structs as:
struct('nestedLevelOne', repmat({struct('nestedLevelTwo',repmat({zeros(1,1080)}, [1,540]))} , [1,100]));
When I access and store data to these structures this is leading memory issues with 192gb ram on my workstation. Is there I am doing wrong with this?

I could generate this nested structure without any issue.
Could you tell us more detail on the process when you faced the memory issue?
By the way, I would recommend break-down your code to be read easily, like:
c1 = repmat({zeros(1,1080)}, [1,540]);
c2 = repmat({struct('nestedLevelTwo',c1)} , [1,100]);
yourStruct = struct('nestedLevelOne', c2);

It takes ~472MB memory as shown below.
a = struct('nestedLevelOne', ...
repmat({struct('nestedLevelTwo',repmat({zeros(1,1080)}, [1,540]))} , [1,100]));
whos
a(1)
a(1).nestedLevelOne(1)
size(a(1).nestedLevelOne(1).nestedLevelTwo)
