My issue is basically identical to the issue here, except that the solution there does not work for me.
That is, libreelec has opened in safemode. I accessed the log file (see below). The log is basically identical to the one in the linked question. However, the solution of "delete or rename /storage/.kodi/userdata/profiles.xml" did not work (I first renamed it, which didn't work, and I then deleted it, which again didn't work). I also tried deleting the file /storage/.kodi/userdata/guisettings.xml (which I found suggested here), which also did not work.
All the log files I got were identical, with only the times differing. The file is:
