Try using a different variable name, I used trials as an example, but trials is actually an important variable in PsychoJS. Try

r += 1;
navonTrials = new TrialHandler({
    psychoJS: psychoJS,
    nReps: 1, method: TrialHandler.Method.RANDOM,
    extraInfo: expInfo, originPath: undefined,
    trialList: 'conditions.xlsx',
    seed: undefined, name: 'navonTrials'
});
    
trialList = navonTrials.getTrialList()    
condition = trialList[r]['trialType']
