I noticed you're in zone 6, where do you live? btw
welcome to the Forum, I live in zone 6B, I have shared
with many gardener's although it's still early, the weather
right now is so unpridictable, just wait another couple months, there are a lot of people that share on this Forum

Wait and see if it might grow back. I've had several that looked totally dead and then sprouted at the base right when I was ready to give up.

I agree that it might very well still be alive. I had a dormant brug in my garage that I'd forgotten about that bounced back after almost 8 months of no water and many others that appeared quite dead that sent up new growth from the roots. As long as the soil wasn't moist and cool it has a really good chance of surviving.

I don't have any cuttings but I will send you a couple of small plants for postage if you send me your address. I can pack them in tubes to protect the foliage and they should be fine. I have lots of Yellow Aurea started and extras of several others.

Like everyone said it is a good chance they are alive. I have done some horrible things to my Brugs and they survived.
