Hopefully, that solved the problem. If the problem pops up again, I have two suggestions.

Carefully clean all of the main battery connections, including the earth connection to the body.

After the next rain, open the hood/bonnet and look down into the black plastic grille near the rear corner of the engine area. Any water in the bottom is a very bad sign. The outlet in the bottom must be cleaned immediately, and you must pull the right-side carpets and check for water in the channel in the floor. The carpets will not appear to be wet - the water will be underneath. The trapped water will cause corrosion and bad connections on the battery cables and main fuses in the channel and under the aluminum panel, and will travel to the SAM (Signal Acquisition Module) and fuse block under the rear seat, causing all sorts of electrical problems - and the problems will just continue to get worse.
