ANSWER:

Taraweeh is not mandatory so you’re not sinful for missing it in the masjid, however you have LOST a great deal of reward.

QUESTION: I missed teraweh and I was installing operating system on my laptop so i prayed after i finished it. Is this work or some else hobby or money earned halal due to which we missed prayer in masjid and delayed salah and should I repeat process I did during that time?

Prayer, Taraweeh, Tahajjud and Qiyam-ul-Layl |
