That basically clears _all_ syntax settings in org-mode. It would
interfere with pretty much any major mode that modifies syntax tables...
A better way to modify syntax table is using modify-syntax-entry or you
need to make sure that your code inherits org-mode-syntax-table instead
of creating an empty table.
I just searched through org code and the following syntax table elements
are being used by org:
-*- mode: helm-grep -*-
AG Results for `modify-syntax-entry':
org-element.el:380: (modify-syntax-entry ?\( "()" table)
org-element.el:381: (modify-syntax-entry ?\) ")(" table)
org-element.el:383: (modify-syntax-entry char " " table)))
org-element.el:389: (modify-syntax-entry ?\[ "(]" table)
org-element.el:390: (modify-syntax-entry ?\] ")[" table)
org-element.el:392: (modify-syntax-entry char " " table)))
org-element.el:398: (modify-syntax-entry ?\{ "(}" table)
org-element.el:399: (modify-syntax-entry ?\} "){" table)
org-element.el:401: (modify-syntax-entry char " " table)))
ox.el:6870: (modify-syntax-entry ?\[ "w"))
org.el:4719: (modify-syntax-entry ?\" "\"")
org.el:4720: (modify-syntax-entry ?\\ "_")
org.el:4721: (modify-syntax-entry ?~ "_")
org.el:4722: (modify-syntax-entry ?< "(>")
org.el:4723: (modify-syntax-entry ?> ")<")
org.el:4838: (modify-syntax-entry (string-to-char (car c)) "w p" st))))
org.el:10927: (modify-syntax-entry ?@ "w" tag-syntax)
org.el:10928: (modify-syntax-entry ?_ "w" tag-syntax)
The last two refer to tag groups.

I hope the above helps.
Best,
