I've had my HA offline for some time due to some changes in my living conditions and have finally got it all ready to set up again.
I ran updates and I'm now stuck on a "loading data" splash screen after 2 days.
I was running 2024.4.2 so quite out of date. Anticipated running into issues.
Would really like to avoid needing a fresh install if possible as this was 5 ish years of continuous tinkering that I'd hate to have to redo from scratch
Any suggestions where to start trying to trouble shoot?
