As far as I can tell, this is not during any holiday or event.
The link you posted is similar but not exact. I seem to have a two-part issue:
1. On my save with an audition already lined up, I go to the audition successfully but when I return home, nothing happens. The audition does not go away and I never get accepted/rejected for the gig.
2. On my save with no audition, I use my phone to check for auditions and accept one. After that, nothing shows up in the bottom-right (see picture) and I am unable to check for any auditions if I queue up the task.
I thought that’s a mod issue but seems like it is not! I sometimes fixed it by letting my sim travel, when arriving on a different lot the audition moved further to the actual acting job
