Media Encoder is telling me there is a warning?

Hi everyone,

I am having this problem and could use some help.  So far I've re-installed Premiere, cleared the media cache, and re-linked the 2 pieces of media in sequence 1 via this method. Right Click clip > Make Offline > Link Media.  I've also restarted my MacBook several times.

First question.  Do I need to consider re-linking all media in the project?  In this particualar sequence, sequence 1, I only have the 2 aforementioned clips.

Second question.  Does Media Encoder prompt the warning if the faulty media exists in a sequence you are not rendereing?  For example if the faulty media is somewhere else in the project, can that cause this issue?

Other things to note

I tried rendering a clip from another sequence (seq 2) that does not include the 2 pieces of media in swquence 1 and I also got the warning/fail to render.  This is where my question about re-linking alll media comes from because I re-linked the media in the sequence I want to output and still get the warning.  Leads me to believe the problem is somewhere else?

I've tried to switch Render quality from custom to VBR 2 Pass, High QUality 1080 and others.

Thanks in advance to this aweome community that has helped me so much already!
