This is a known limitation of the shadowing method.

Practical solution (to work around the limitation):

increase the suns shadow clip end to 50m (will get rid of the artifacts on the right side)
decrease the suns shadow softness to zero
increase the suns shadow exponent to something really high (e.g. 1000)
put a solidify modifier on the walls (can be negative/outwards so it doesnt change your framing, e.g. -0.03, preferably with "even thickness" turned ON)
