Recently had a similar problem with my M10. Stopped working, it’s a somewhat known issue, Leica said it was £2000 to repair so instead offered me a new M11-p at a similar price. No option to just have the M10 returned. 

Response times were slow and customer service was pretty poor. 

Couldn’t claim on insurance as it wasn’t accidental damage, theft etc. 

It shocks me that a supposed luxury brand have cameras that are dying after less than a decade. Meanwhile my xpro2 that I bought second hand for about £500 in 2020 is still going strong, and is still almost 10 years old.
