Boruta Python No feature Selected

I run Boruta with RandomForestClassifier the previous day on my data (nb features = 36) and got 17/36 confirmed. Now I run it again and there is 0/36 and stop at the 9th iteration. Any idea why this is happening?

%%time
rfc = RandomForestClassifier(n_estimators=200, n_jobs=-1, class_weight= 'balanced_subsample' , max_depth=10)

boruta_selector = BorutaPy(rfc, n_estimators='auto', verbose=2, random_state=1)

boruta_selector_before.fit(X, y)

the current output look is the follow
