Can't save project.. need help

i did not change inputs, and read other post, then clear cache. but still can’t save pjoject help

are you logged in under your Epic Games account in RealityCapture? Were you saving this project after some steps? Do you have set Autosave?
What were your exact repro steps to achieve this error?
Is this also happening for other datasets?
Can you try Clean install?
These steps are not the same as when you will reinstall the application just by installation file.
Please try to “make it like a clean install” (this will reset your settings to default in the process):
In order to do that:

  • Shift + Double LeftMouseClick on RealityCapture icon
  • From drop-down select make it like a clean install and press ok
  • Then try again
