The empire was overtaken by the Catholic Crusaders in 1204 AD, but it was taken back in 1261 AD. It was weakened, but it did not disappear.
During the Crusades, the Byzantine Empire was a crucial player, particularly in the First Crusade (1096-1099). The empire, under Emperor Alexios I Komnenos, sought military assistance from the West to reclaim lost territories from the Seljuk Turks. However, as the Crusades progressed, relations between the Byzantine Empire and the Western Crusaders became strained, leading to tensions and conflicts, notably during the Fourth Crusade (1202-1204), which culminated in the sack of Constantinople in 1204, severely weakening the empire.

The KIevan Rus' attacked Constantinople and the Bosphorus.
Yes they did. They managed to conquer Constantinople in 1204 and formed The Latin Empire of Constantinople until 1261 when The Emperor of Nicea reconquered the City for The Byzantine Empire.
The crusades, originally intended to save the Byzantine Empire, among other things, failed to do this and hastened its decline instead. The crusaders sacked Byzantine cities and eventually captured Constantinople in 1204. They then used Constantinople as the capital of what is called the Latin Empire, which it remained, until the Byzantines managed to recapture it in 1264. The Byzantine Empire never really recovered from this, though it held on for almost another 200 years.
The Fourth Crusade, which took place from 1202 to 1204, did not make it to Jerusalem. Instead, the crusaders diverted to Constantinople, leading to the sack of the city in 1204, which significantly weakened the Byzantine Empire. The original goal of recapturing Jerusalem was overshadowed by political and economic motivations in the Byzantine capital.
