Premiere 2020 black screen - reoccurring issue
Our video editing machine is having continual issues with the black screen / no timeline playback issue. I am running out of ideas to fix the issue after endless googling and troubleshooting... any further ideas would be appreciated.
Specific issue:
- Black screen in playback
- Timeline doesn't move
- Audio plays
- Premiere process will not close properly (must be End-Tasked) no matter how long you wait (closes properly when this issue is not occurring)
This issue affects the whole program (usually) not specific projects. I.e., when it occurs, the whole program will be unusable until we can fix it. The projects will still work on other machines.
We are currently on nVidia Studio drivers ver. 441.12 (I'll once again be trying to update to the latest after the user is done with other work on the machine, but changing drivers hasn't previously seemed ot have any effect)
Projects are usually worked on off of the dedicated 1TB nvme drive set aside for video editing/scratch disks in the machine (I was also going to throw a spare 512GB nvme in to dedicate to scratch disks just because we don't have another use for it, but I don't want to play with too many variables before figuring out the issue...). However, projects being on the network or local doesn't seem to make a difference, the Black Screen issue just started again, and the files were on the network, last time they were local.
- Switching Mercury Playback GPU acceleration on or off has no effect.
- Trashing preferences has no effect.
- Clearing media cache manually sometimes does, I don't want to have to do this every couple of days though... want to figure out what's causing corruption...
- Disabling antivirus seems to have no effect.
- Resetting workspaces has no effect.
- Uninstalling and reinstalling premiere with the CC Cleaner tool has no effect (this apparently still doesn't remove media cache files???)
- Memtest 86 was run by us and our IT company and found no issues with the RAM.
- Our IT company found no issues with the SSDs or other hardware, and performed every cleanup they could on the machine. This worked for about three days and the issue reoccurred.
System:
Win 10 pro 1906 update (issue occured on previous updates as well)
i9-9900k
64GB 3200mhz Ram
RTX 2080
512GB SSD Samsung 860 EVO (OS)
1TB SSD Samsung 960 EVO NVME (For project files / cache / scratch disks)
Anyone else having similar issues with (I assume?) the media cache getting constantly corrupted in Premiere 2020? Or with black screens occuring repeatedly affecting the whole program not just specific projects, and seemingly not just connected to Mercury GPU playback?
Other troubleshooting steps we haven't thought of, maybe?
