Stuck in boot loop after software update

Hi Garmin brains trust,

I’ve had my trusty 955 for nearly 2 years and it appears that a recent software update (18.26 I think?)  has got me stuck in a boot loop.

I managed to get it out of a boot loop a few days ago with a hard reset, however something must have changed a couple of hours ago as my watch has gone back into a boot loop.

I’ve tried hard resetting a number of times now, however it won’t get out of a boot loop now. I’ve connect to my PC to try and bring it back to life with Garmin Express as well, but the watch isn’t even recognised by the PC.

Any suggestions?
