like i said in the video in older versions this can also occur because one of your saves does not have a thumbnail image
if ur having a similar issue in a version below tu60 try to copy a thumbnail image from another save and put it in any save folder that has no thumbnail image in it
0:00 -virtual machine
0:11 -issue
0:18 -quick fix (no saves)
0:56 -long fix (saves)
in short
.downgrade to a title update older than tu60
.load this tu in xenia (should boot fine)
.go into world select and delete (or load and save) all saves without a thumbnail image
.reinstall whatever TU you want that is after TU60

or if u dont care about ur saves just move them to a new location in your file system
