Can't say I've had that problem (5 languages). My problem has been that what I call "language confidence" erodes quickly when you don't use them for a long time. For example, I use English and Spanish on a daily basis. No issues there. However, I haven't used French for probably 30 years and German for 20. I can listen to both and understand most of it, yet launching into speaking anything other than short phrases feels really uncomfortable. Tangent: I learned some Japanese years ago. The language made sense to my brain. No writing, just conversation. The same thing did not happen when I attempted to learn Chinese. The way I put it is that my brain simply could not synchronize with the speech pattern and sentence structures. To be fair, I don't think I made a solid effort.
