You cannot use forge with 1.14. Please wait a few months and give the forge team time to update it to 1.14. As Oval stated, please include a crash report.
Try running it without forge, as that is the cause. I can run it just fine.
The Multishot enchantment is like Infinity, it takes 1 arrow and shoots 3. You can only pick 1 up as if you could pick all 3 up you could easily duplicate arrows. Can a mod please close this non-issue?
