I have the same problem. Last year, around September 2022 EiG-function worked great for me. Now it doesn't anymore, as I discovered yesterday. I can create a new world, edit with all the functions in CAW, but if I try EiG EA desktop pops up and tells me the game failed to launch. Very frustrating. I've tried reaching out to EA, but they are not really likely to give any helpful answers about this.
Something very strange is also happening, when I try editing a new (created yesterday) world what I described above happens, but if I do the same with a world I was working on last year (between May and September) the EiG kind off works. It launches at least, and allows me to edit like normal until i try to save and exit back to CAW when the save fails. The graphic settings are also completely off, they revert back to the standard settings, and since the save fails I can't restart the game as it needs when making changes in the graphics... aaand for some reason launching EiG messes with the settings I have in the full game too. Very, very confusing. Has anyone experienced this as well?
I saw a reddit post ( https://www.reddit.com/r/Sims3/comments/15l619u/fir_island_not_yet_finished/ ) about CAW where two people claimed EiG works again, but as of today it still doesn't work for me. Have anyone gotten it to work again?
