Disabling adblocker worked for me, thank you!
What worked for me is the entities page for some, and deleting the others from .storage/core.config_entries (not the entity registry, as they didn’t have entities) on HA 2024.11.1
I can confirm that is the browser cache. Instead of deleting my cache, I switched to another browser and I was able to delete the helper. I think it also might work to open an incognito window. Since just switching from Safari to Chrome worked for me I can’t say for sure.
thx Ctrl F5, fixed it
