Smarthings - 500 Internal Server Error Server got itself in trouble

I can’t add integrations or install upgrades. I can’t repair with “Close down HA, delete config/.storage/smartthings, restart HA” because I don’t have smarthings file in .storage directory. Please, help.

You might get better response if you add ‘Smarthings’ to the title.

With the core_2024.2.5 restore, I regained access to google calendar. I still can’t do integration upgrades.
