As subject I was done my editing and export a version to check. And the Premiere pro's (23.4) monitor just been whole black. I couldn't find out anyway to solve it. I try to turn off multi-cam and it just solved.

But I need multi-cam to put different cut on the film. 

My pc setting:

i7-12900KF

GPU RTX2060
RAM 64GB
Premiere version 23.4

Another problem here:
My film length is 18min. When I was editing and put some picture and text, it was just been lagging and slow to preview.

We'll need some more info. What type of media? H.264/5? HD/UHD, etc... 

Did it ever work, ie: you sure you have the multicam created correctly? You then created a sequence right-clicking the multicam source in the project and selecting "New Sequence from Clip". etc...

Also you could try deleting your cache. Start PP holding down shift as you do, and then respond to the dialog.

I was nest the source from timeline and enable multi-cam as usual.

I was deleted the memory cache when I found the program getting slowly. And also make the media proxy for editing.

My problems that program lagging and monitor got black didn't happen when I was using the elder version (22)
