I downloaded a layer from a public website and I want to align the layer with OpenStreetMap. To do so I set the project's and OSM's CRS to the CRS of the layer. However, it appeared far from its expected place.

Moreover, the layer came with a brief pdf that stated it's a Krasovsky_1940_Equidistant_Conic projection. I tried already to apply the EPSG:4024 - Unknown datum based upon the Krassowsky 1940 ellipsoid but there was no improvement.

I tried other different combinations of CRS but so far nothing worked out... Result of setting Project CRS and OSM CRS to layer CRS (ETRS89-LAEA5220)

The ".prj" file of the layer has the following code:

GEOGCS["ETRS89",
DATUM["<custom>",
SPHEROID["GRS_1980",6378137.0,298.257222101]],
PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],
PROJECTION["Lambert_Azimuthal_Equal_Area"],
PARAMETER["False_Easting",5071000.0],
PARAMETER["False_Northing",3210000.0],
PARAMETER["Central_Meridian",20.0],
PARAMETER["Latitude_Of_Origin",52.0],
UNIT["Meter",1.0]]

    Never, never, never "set" the coordinate reference of a layer that has one. Doing so effectively lies to the software, and it's gullible enough to believe you, and that will trash your map. Instead, you need to project, or transform or change it (the terms are slightly different across platforms) to a new coordinate reference. Repairing this can be as simple as setting it back to what it was, or reacquiring it as necessary, then transforming it correctly. – Vince Feb 11 '23 at 02:05

    Since this is another version of the most common Question on this site, I've voted to close it with the canonical QGIS flavor as per the meta guideline -- Layer disappears when changing from CRS in degrees to CRS in meters in QGIS – Vince Feb 11 '23 at 02:17
