Premiere Pro CC 12.0 randomly crashing several times a day
I am running an iMac (late 2015):
-i7 4gz
-32gb
-Radeon R9 M395X 4gb
-OSX 10.13.2
My files are, exclusively, from the Sony A7R2:
-XAVC 25p/4k .mp4 -files
I don't have grades on the clips, just dropping selected clips onto the timeline and trimming them. Very basic edits.
I'll take a 5 minute break, come back to the app and it tells me it has "encountered a serious error" and it will attempt to save my work. It always takes me back 2-3 hours, at least, if I haven't been saving all the time. Which I should, I know that of course.
So, in a nutshell, the crash seems to happen when the program has been idle for, say, more than 2-3 minutes at a time. I can't figure out any other repeating patterns that I've done that would lead to said crash. During these breaks I do not use the computer for other tasks.
However, this is highly annoying and frustrating for a working professional with deadlines to meet. I can't keep adding hours into my workflow just because the program has some unknown issues and I'm already starting to consider jumping ship from Adobe to something else. I don't want to do that, but I am running out of options and/or patience.
Anybody else experiencing the same problem?
