Everything runs fine in the editor. Other threads have suggested I need to rebuild my project but I am hesitant to do so. Does this stand out to anyone?
nvm, a rebuild worked. That is:
1: verify engine in the library tab of the epic games launcher
2: delete everything accept the config, content, plugins, source, and .uproject files/directories from the project folder as outlined here: Regenerating Unreal Engine Project Files - How and Why
3: right click .uproject file and select generate visual studio project files
4: open .uproject file and select build
