Launcher crashes when I open the downloads tab in Sims 3

Hey all, 

Apologies for the delay in getting back to you here.

This issue was reported up to The Sims 3 team for investigation in May, who determined that these issues were ultimately caused by changes Apple made starting with macOS Sequoia 15.4.1.

We've engaged with the relevant teams at Apple to investigate further but have no updates beyond that at this time. 

In the meantime, some players are finding success with the workaround missfelicityk​ shared here.
