Last UI Exception: PackIconCellView

Update on October 24th, 2021:

I've sought help for this on two discords, as well as Answers HQ, and I have now also posted on the Sims 4 forum because I have yet to pinpoint the cause. I am playing an unmodded, vanilla game but am still receiving a Last UI Exception. To my knowledge, an unmodded game should not be causing Last UI exceptions. The nice folks at the discord said my Last UI exception is typically caused by a gallery feed error or mods, but I have no gallery notifications to clear (I regularly delete them) and as I mentioned, no mods. I have tried deleting cache files as well as repairing the game.

If anyone had any idea what could be causing the issue, I would appreciate feedback.

I'm concerned that continuing to play the game without fixing the source of the issue will lead to a corrupt save file.

Thank you!

Below is the Last UI Exception:

Update 1/3/2022:

It is now January 2022, and I am still afraid to play my game due to the recurring Last UI Exception error. I don't want to put a lot of work into a save file only to discover it is corrupted because of the Last UI Exception. Yes, I have backups, but I am afraid to put further time and effort into a save if it is having an issue.

I have continued receiving the Last UI Exception with Cottage Living.

I have no mods.

I have tried deleting cache files and repairing the game.

As mentioned before, I previously had an issue with Last UI exceptions even with no mods, but that was temporarily fixed after deleting my notifications in the upper-right hand corner of the game (this was suggested to me on a Sims 4 Discord). I was regularly deleting notifications to prevent that Last UI exception from happening, but now I have the Last UI Exception again.

I must admit that I am very frustrated with this happening. I don't understand why I am getting a Last UI exception, because according to what I have read online, those are typically caused by mods, and I have none. I appreciate the support of volunteers and SimGurus on the forum who try to help. Like many players, I have invested a lot of time and money in this game, so it is frustrating when it doesn't work.

Does anyone know what may be causing this Last UI exception? And if not, do you have any idea of things I could do to troubleshoot (other than the things I have attempted above) to fix the game?

Thank you in advance for your time and support!

Hi @crinrict - I am still in the process of setting up my game worlds to my preference, but I haven't noticed anything, I just see the Last Exception UI after I log out of the game and go into the game folder.

Hi @crinrict - So even if it is the same Last UI Exception occurring over and over again, most times that I play the game, it is a possibility that it is nothing to worry about?

Hi @crinrict - thank you for replying! I appreciate your help.

I will operate under the assumption that it is fine, and just an error with the EA code, since I have reinstalled and repaired multiple times, and currently have no mods, But I will follow your advice and continue to keep frequent backups, just in case.
