Measures ought to have been taken to prevent the spread of COVID in Liturgy, but making it so that no one who are of the flock of Christ could attend Liturgy where they could receive Communion is not the work of the Good Shepherd. It's the work of those who are not. Most of the people were too afraid to want to come to Liturgy, and especially receive Communion anyway, so the typical parish would only had to have Communed a small handful of people each week. Many parishes did not even try. Bishops were afraid of priests getting sick, because they struggle to supply priests to parishes in many diocese and can't afford to have fewer priests than they already have. Thus, bishops forbade their priests from having Liturgical services with people present. Priests may have been afraid of getting sick themselves, so that they didn't want to hold Divine services and put themselves at risk. Many, I'm sure, thought and felt that they were doing what they needed to do to protect the people they serve from getting sick and perhaps dying or to protect the institution of the Church. That is understandable to a degree. However, Christ, His Apostles, and His saints have all preached the Gospel to many people, and the Apostles and priests have Baptized countless Christians throughout the age of the Church, while knowing full well that by making them believers in Christ they were also putting their mortal lives in danger. Missionaries die while journeying, either by accident or sickness, or by being killed by hostile natives or non-Orthodox Missionaries. Lay believers are also imprisoned, tortured, and killed because they believe Christ and keep His commandments - especially the commandment to eat His body and drink His blood. In light of this truth of history and Tradition there is simply no real excuse for interrupting the Holy Tradition over COVID. If a person chooses to receive the body and blood of Christ in the face of peril, whether from persecution or disease, then let them do so.
