@lavalamplighter said in RetroPie crashes after attempted update:
preconfigured game box several years ago.
It is not practical to troubleshoot a system that neither you nor we have any idea how is configured. For this reason, third-party builds are not supported in any capacity.
Start here: https://retropie.org.uk/docs/First-Installation
I suggest you to backup if able your existing roms, and then install the current latest official image for your hardware from the website at https://retropie.org.uk/download. After the new version is installed, you can restore the backed-up roms to it.
