Description

System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 432.00

Blender Version
Broken: version: 2.90 (sub 0), branch: master, commit date: 2020-05-07 21:33, hash: rBc6cda3c09cd0
Worked: (newest version of Blender that worked as expected)

Short description of error
the multires normal baking does not seem to work for both 2.83 or 2.9
It seems to use the preview rather than the render, also it produces a worse bake the higher the level/subdivisions.

When trying to bake file you uploaded there was error: Multires data baking requires multi-resolution object

Please upload correct file or provide exact steps to reproduce.

The visibility checkbox in the multires modifier is disabled thats why it wont bake.
I was here to search for a solution to this error (Multires data baking requires multi-resolution object) because i have it in a different file too. But there is no bug report for it so i guess i made something wrong..

Regarding this bug report, this seems to be the way it has always worked:

Baking normal map from Multiresolution modifier data relies on the difference between the viewport number of Multires subdivisions and the highest level it was subdivided to.
