Is performing the Fajr prayer at home, under the circumstances of the coronavirus pandemic, sinful, especially if the congregational prayer is missed and the prayer is performed at its appointed time, approximately half an hour after the Adhan?

We bless the questioner's eagerness to perform prayer in congregation, and we urge him to prepare for prayer before the adhan (definition) (call to prayer) in order to catch it in the mosque. We reassure him that there is no sin upon him if he misses the prayer in the mosque due to its distance or the mosque closing immediately after the iqamah (definition) (call to commence prayer). He is rewarded for his eagerness and attachment to the congregation, and we remind him of the devotion of the righteous predecessors to catching the first takbeer.
