Edit: Bump
The best way to apporach this is by accessing the addon folder and moving whatever add-ons you have installed to a temp folder. Try running the game again if the problem still exists, then perhaps it's something internally (drivers/software from your PC)
If the problem goes away, try moving one by one and add-on to see if still runs. Next time perhaps it's best to post PC specs before anything so your question can be answered hastily.
