Sim immediately cancelled Programming Actions

Hi,

I'm having this same problem.  Programming stopped leveling during level 4 at about 45%.  Nothing in the Tech Guru's "Program" options are working, they either do nothing when selected or just disappear immediately from the task list queue (e.g say you're eating and then select a programming task, sometimes it will show as queued in the task list.but when it comes to performing the task it immediately disappears.

I've tried:

1. Going to a different lot.

2. Backing up / deleting my sims 4 folder and copying back the saves, Mods, Tray, Custom Music directories. (this was a suggestion elsewhere).

3. Quitting my job and then finding a new one (both still Tech Guru).

4. Changing the chair.

5. Trying one of those cheat codes to increase the level to 10.

I haven't progressed overly far in my Sim world so don't expect anything magical, I"m new to the game, but the saves directory for mine can be downloaded from here if you wish to take a look (The character "Dave" is the one with the problem):

I should note that I don't have any mods or anything, other than simsync.  But it happens standalone too without simsync.

Cheers.
