I had a Hackberry tree struck by lightening about 6 years back.
The next day I cut it down and started roughing out staves, only to find, tiny fractures all throughout the wood,
"and by throughout the wood I mean in every growth ring layer"
The tiny fractures looked like checks from natural drying.
I proceeded as normal to attempt to make bows from this wood.
Once the bows were floor tillered and on the tiller tree, you could hear dozens of little ticks when the limbs flexed.
The tiny fractures continued to run the length of the limbs and split each time the bow limbs were flexed.
I was VERY disappointed, as you could imagine.
Seems that the lightening either
A. Instantly sucked all the moisture out of the wood, and caused the fractures, or
B. It Superheated the moisture and caused the wood grains to expand and crack due to internal pressures.
Maybe lightening has different effects on different woods, maybe it's the amount of voltage applied to the wood.
Too many unknown variables
I have made many bows from many other Hackberry trees since, and have never seen the tiny fractures in any of them.
I hope this is not the case for the wood you have, But I would check it closely for tiny fractures.
Good luck and I hope things turn out well for you.
