Conda environment lock file hash mismatch

I have a Jupyter notebook that used to work, and runs through all of its cells successfully from the Jupyter UI. But when I Sync it and try to build the dataset, I’m getting a build error stating that the build failed due to a mismatch in the Conda environment lock file hash. AIP gives me suggested conda commands but I’m not sure where to run them; I don’t normally have to intervene in the environment.
What is this conda error and how do I resolve it? Restarting the kernel doesn’t help.

*Bonus: This program creates files like .pptx programmatically. I have a cell that then copies the .pptx into a Dataset. When I run in Jupyter, I can see the file .pptx created in the directory, but Jupyter behaves almost like it is on a branch in the sense that running the code in Jupyter does not populate the Dataset, I have to actually Sync and Build. For testing purposes, I can open a .jpg from the Jupyter view by clicking on it, but there seems to be no way to get a .pptx from Jupyter. It would be less confusing if running from inside Jupyter was the same as running a Build instead of being a “phantom run.” Logic behaves similarly, you can run a logic but you have to call it as a function to actually change ontology.
