Sounds like one of the struts is deformed and too far out of spec to get the alignment right. If thats the case you better check if the strut is damaged beyond repair. Might be possible to fix it or get a replacement from a salvage yard. If it is not too far off, you might get away with changing the alignment on both sides so they are out of specs but probably still drivable (should be the same setting on both wheels though). Check racing specs for your car to see whats a proper range for the alignment. Factory settings are pretty conservative most of the time.
