The Nigerian Youth Movement (NYM) collapsed because of

The Nigerian Youth Movement (NYM) was formed in 1934 to fight for political representation and social justice for Nigerians, particularly the youth. However, the movement collapsed because of leadership struggle among its leaders who could not agree on the best way to achieve the goals of the movement. This led to factionalism and infighting which weakened the movement and made it ineffective. Additionally, there were allegations of corruption and nepotism within the leadership which further eroded the trust and support of the members. The government ban on the press also contributed to the decline of the movement as it was unable to disseminate information and mobilize the public effectively. All these factors ultimately led to the collapse of the Nigerian Youth Movement.
