It is not unlikely that you have an angle like this:
but look at all the answers; some useful information there.
Also like always check for double vertices, so select everything and M merge by distance. Make sure you applied your scale and lastly make sure you don't have flipper normals, so in the overlays turn on face orientation, if you see a red face, select everything in edit mode and Shift + N to recalculate normals.
