I have a .mxd that I created in desktop 10.6.1. I am trying to change raster symbology and my document continually crashes. I have opened an .mxd created in 10.5 (with a similar raster whose symbology I had changed previous) this also crashes in 10.6.1.
These rasters are .asc containing geophysical data exported from other software which is then georeferenced in Arc. I can geo reference fine. This problem also arises even when they have been imported into .gdb and I try to display from there.
