This seems to cause:

    INFO     Scraping files for loaddefs...85%
  typescript-ts-mode:0: Warning: Not registering prefix "ts".  Affects: 
("tsx-ts-mode--indent-compatibility-b893426" 
"tsx-ts-mode--font-lock-compatibility-bb1f97b" "tsx-ts--s-p-query" 
"tsx-ts--syntax-propertize" "ts-ts--s-p-query" "ts-ts--syntax-propertize" 
"ts-ts--syntax-propertize-captures")

Stefan, what do we usually do with such warnings?
