Below is from Bambu’s TDS for various filaments. Not sure if that is the problem you have (can’t really see the print quality from the pic), but they are not wrong. Wood PLA Hoovers up moisture, and summer can be a very humid season for some people.
PLA - 0.43% absorption rate
TPU - 1.08% absorption rate
Wood PLA - 1.25% absorption rate (nearly 3 times worse than basic PLA)
