Crash happens when 2 stacks of any block are put into quantum chest.
Specifically it creates a ticking entity that then crashes the server.
Below is the crash report.

Due to limited support for 1.10.2 please, use https://minecraft.curseforge.com/projects/quantumstorage mod. TR will detect that QS is there and will not register TR own quantum chest.
