A downgrade “works”, because pyarrow is part of 0.63 and Components. The point is just to be able to pass dataframes to the front-end, I don’t know that we necessarily need a specific version.
Seeing the PEP517 message though and Googling brought me to:

Is Raspberry Pi a 32-bit system? It sounds like Arrow has an issue here with 32-bit and pip.
