bad cpu type in executable

[chienMouille]

Hi,

I'm not understanding much of what's going on in the background, so apologies if obvious, but lately I get this error trying to upload sketches on Arduino boards with Deviot.
I'm running a Mac on Catalina 10.15.7.

Any idea how to solve it?

Thanks a lot!
