Are you able to change the log settings? I had a similar issue, although not caused by the upgrade, where my logging stopped. the file org.ops4j.pax.logging.cfg was empty and all the Add-on Settings were blank. I follewed the the guidance at https://community.openhab.org/t/my-logs-broke-today-not-sure-why/141647 from @Udo_Hartmann and then all the addon settings reappeared.
