Ideas
I'm having the same issue. My game is fully updated, and I ran a repair after having some issues with UI - unknown if related.
I've been getting the select favorite season every time I travel, and just selected one and kept playing. But when I tried to purchase a lot for a small business, I ended up in a loop where I select a season and click accept, and the season selector re-appears. I tried restarting the game, but the same loop happens.
About the UI issues. I'm not entirely sure, but I think these issues appear when I'm traveling - but not always. The bottom part of the UI disappears, and if I try to open the map, the screen pauses but nothing happens. I also cannot interact with things/sims as the option menu doesn't open. I can still access the settings/save game/quit menu. Issue resolves upon restarting game - until issue occurs again.
