What it means
Potty means a bit mad or daft, usually said with a wink rather than malice. If someone’s gone potty, they’re doing something odd, overexcited, or a touch unhinged in a harmless way. It’s an old-fashioned, family-friendly put-down you’ll hear from older Brits, often right before they offer you a biscuit and a look.
Usage examples

"Auntie Mavis has gone completely potty about competitive Scrabble since the cousin lent her a Collins official dictionary in March, she now travels by coach to the regional tournaments in Worthing every other Saturday and writes down obscure two-letter words in a small black notebook between rounds."
"My nan is properly potty for the gardening centre on the ring road around Telford, every Tuesday morning the bus stops outside her bungalow at quarter past nine and she returns with six new plants, three bags of compost and a porcelain hedgehog ornament from the gift shop counter."
"You spent two hundred quid on a vintage toaster because it had nice vibes? You’re potty, mate."

Where it comes from
In the mad or daft sense, potty is old British English, around by the late 19th century. It’s widely linked to cracked pot and the older idea that a damaged pot meant a damaged mind. That gave it a soft, domestic feel, so it landed more as teasing than a vicious insult.
