This started happening to me too yesterday. I'd been playing in the same save, visiting the maker space almost daily, sometimes multiple times a day, with no issues and then this happened suddenly. I had made no changes to my game at that point (hadn't taken the update, hadn't added any new mods, my save was in a steady state)
I removed all my mods, repaired my game, cleared my cache, replaced every single lot type on the Port Promise community space with fresh ones from a fresh base save and it almost immediately bugged out again.
I had to take the update to do the repair and since the Maker Space was unsalvageable I spun up a new save. Went to that maker space for the first time and it bugged out in the exact same way when I exited to manage worlds and tried to come back. From what I could tell it seems to have something to do with leaving the lot with unfinished fabrications in the fabricator. My sim was in the middle of a fabrication when I went to manage worlds and in my HOURS of testing of multiple backup saves yesterday to try and fix the issue (the issue seems to persist across saves once it starts) I noticed I couldn't bulldoze the lot if there was a fabricator with an unfinished project in it. I'd get an "this object cannot be deleted" type error.
This is absolutely game breaking for Eco Lifestyle (and this was my single pack, Eco Lifestyle only, playthrough) I hope someone will look into it soon.
