This may be due to the update from pre 1.0. The layout system got changed and 1.0+ layouts are not compatible with pre-1.0. Try going to C:\Users\[USERNAME]\AppData\Roaming\Pixelorama\ and deleting the layouts folder, and launch Pixelorama again.
i tried building from source code but even that didnt work
i think this is because of 1.0
i went back to 0.11.4 and it showed. is there a way to use 0.11 layouts with 1.0+?
0.11 layouts are not compatible with 1.0 and vice versa, unfortunately.
