Create strip trial points - issue

I'm trying to create a strip trial points to run the moving t-test I'm getting the following error:

An error has occurred while executing Python code: 

UnboundLocalError: local variable 'out_crs' referenced before assignment

The raster and shape files were on WGS84. I tried converting it to a different CRS. Then the above error didn't show, but two other issues arised. One (not really a big deal) but the 'Lines Shapefile (Optinal)' was not really optional, I couldn't advance without setting it to be saved. The actual issue is that a different error shows up.
