Kernel Panic in PS

Had an issue last week and had to reinstall macOS from scratch. In the process I updated to 10.14.4 and all seems to be ok but I've had a kernel panic a few times while changing an image size in PS. Always on same task. Details below. Can anyone shed any light on it as I'm not sure what the actual source of the issue was or if it is fixable. Why possible memory corruption?
This is the main top part of the panic report. I have left out all the rest as I didn't think it was relevant but I can post if needed. Thanks in advance.
