How to fix misalignment of google maps and CK63 maps in QGIS?

Question

Cartography

Good afternoon, there is a map of the city in the CK63 coordinate system, which is open with a layer. We want to connect here the map of the city from Google Maps. When adding the latter through XYZ Tiles, the offset of objects relative to each other is obtained (screenshot attached). I understand that because of the fact that different coordinate systems. Is it possible to bring these two systems together in QGIS or what to do, advise and do not kick much)
