HAOS. Error while loading page lovelace

Good afternoon
I have a problem loading the Lovelace page. It seems it started after sudden power outages. I have HAOS installed on the Proxmox system and also installed Mariadb on Proxmox. The problem appears in different browsers from different computers. Rebooting HAOS/Mariadb/Proxmox does not solve the problem. At the same time, everything opens correctly from the application on the phone, as well as from the browser on the phone.

Which web browser is that?

Have you cleared your cache?

I try firefox and chrome from different computer. Yes, i try to clear cache too.

Does anyone have any ideas on how to fix this?

If that’s the case, I’d bet you’re dealing with data corruption - My gut says you’re restoring your most recent backup… Sorry.

I’m at a loss. All other feauters work fine. From phone i can view lovelace and history. This looks like everithing ok. Tuday i am install update 2023.11.3 but it`s not resolving my trouble
