In the aftermath of the
2021 Myanmar coup d'état, she actively engaged in the anti-coup movement, participating in person at rallies and leveraging her social media presence with 2.8 million followers. Thinzar joined the "We Want Justice"
three-finger salute movement, which originated on social media and has garnered support from numerous celebrities.
Arrest On 6 July 2022, Thinzar was arrested after her visit to the headquarters of the
Shan State Progress Party (SSPP). During the visit, she was reported to have attended a wedding ceremony wearing an SSA military uniform in the presence of Colonel San Suh of the Shan State Progressive Party/Shan State Army. The junta's army was in conflict with the SSPP/SSA in the
Momeik area of northern Shan state at that time, and her visit to the SSPP headquarters sparked criticism from pro-military groups. A statement from SSPP Info mentioned that the Shan State Progressive Party/Shan State Army (SSPP/SSA) had extended an offer to document local development projects encompassing religion, education, health, and transportation. However, pro-military lobby groups led by
Han Nyein Oo, suspected to be a military spy, are urging the junta army to permanently halt Thinzar Wint Kyaw's involvement in modeling and entertainment. On 5 August 2022, the military junta initiated a legal case against Thinzar Wint Kyaw and model
Nang Mwe San. The duo is accused of harming Myanmar culture and disseminating sexually explicit photos and videos on social networks. As per an announcement by state-controlled media
MRTV, they have been arrested under Section 33(a) of the Electronic Law for earning money by posting sexually revealing photos on websites such as
OnlyFans and Extrania. In December 2022, she was sentenced to 5 years in prison by the military court. On January 4, 2025, she was released from prison through a pardon to commemorate Independence Day. ==Selected filmography==
