Upgrading to High Sierra with versions of MacWise prior to 16.2.3 could possibly cause abnormally large window sizes and a crash that corrupted the MacWise settings file.
It is unknown why this happens and it seems to be a problem on a low percentage of Macs.
Version 16.2.3 or later fixes this problem by detecting incorrect window sizes and sets them back to default sizes.
If possible, you should upgrade to MacWise 16.2.3 or later before installing Mac OS High Sierra or later to avoid the crash.
