iMovie 10.0.8 crashing 3 seconds after opening
Every time I open iMovie, it crashes "unexpectedly" immediately after I get a notification saying Share Failed. FF transcoder unshare operation failed iMovie theater. It was perfectly fine before today, but just began crashing out of nowhere even before I updated to 10.0.8 (also did that today in hopes it would fix my issue). I've already done most of the common fixes: repairing disk permissions, resetting the PRAM, checking for zero byte files in transcoded media folder, deleting the .plist file in Library / Preferences, and I looked for the 3ivxvideocodec file in Library / Quickts perfectly fine before today, but just began crashing out of nowhere even before I updated to 10.0.8 (also did that today in hopes it would fix my issue). Everything is up to date.
Does anyone have any other suggestions of things I can do to resolve this issue?
