One more easy item to check
interior fuses (drivers side part of light switch)
I’m not sure if you were in this area before or after your problem started.
if you had loosened the fuse block before the lights went blank, the issue may be tied to the fuse block.

Could it be the harness that attaches to that fuse block or the fuse in cavity 11 may be at issue (that fuse also appears to power the licence plate light. Is the license plate light working?
Another guess but it may be worth investigating. Again zero cost inspection.
hoping for speedy resolution on your issue
