Nothing lining up here. Little help?
The 3 on R7 can be the last squares of the 4 so that doesn't narrow anything down
The gap in C13 could be either filled to complete the 5 or blank to end the 5 and start the 2
Top-left corner seems to work fine but there isn't evidence that either filled or blank *doesn't* work which is what in supposed to be looking for w edge solving afaik
