Black screen after updating retropie

[llivingst]

I updated retropie on my rasperry pi 4 after not having used it for about a year. Now when I boot it, it shows some of the logs at the beginning, but stops just before the emulation station logo, with a black screen, my monitor no longer even recognizes the device as connected at that point. switching to safe mode did not change anything. I haven't been able to find any fixes online that apply to my situation, and I can post logs if that helps.

@llivingst I ran into a similar issue when I updated a year old build on my pi 4. It would get to emulation station, but went to a blank screen when going into a game. It think it was crashing cause I could not exit back to emulation station or my video feed was gone. I know a lot of kernel changes were made, so maybe you have a custom configuration that interferes with the new kernel. But Step one would be to try switching hdmi ports. I remember that being in the wrong port did that before. If not, you might have to reimage a new build. I changed all my custom configs from overclocks to KMS drivers switched back to and still no go.
