Neither sentence is entirely correct, but with a few adjustments, they can be fixed. Here’s how:
Corrected Version 1:
"The thought may constitute an obstacle that hinders many people's growth."
Explanation:
"constitute" vs. "constituted":
Use the base form "constitute" because "may" requires the verb that follows to be in its base form.
"May constituted" is incorrect; it should be "may constitute."
"people's" vs. "peoples'":
"people's" is correct when referring to the growth of many individuals (general usage).
"peoples'" refers to multiple distinct groups or nations (e.g., "the world's peoples"), which isn't what you intend here.
Final Corrected Sentence:
"The thought may constitute an obstacle that hinders many people's growth."
