Output variable does not generate results for all thermal zones

Hello! I am using EnergyPlus 9.1 and I am using the AirFlow Network function. I need to generate the operating temperature results of 356 thermal zones. However, after finishing the simulation, when I open the .csv file, I don't have the result of all the thermal zones. This has happened twice with different files. I did a test running in OpenStudio and the result of the average temperature of all zones comes out there, but energy plus does not come out. I would like to know if there is a limit of thermal zones in the model, or what other error could be happening so that the temperature result in all thermal zones does not come out through Energyplus.

Excel used to have a limit of 256 columns, so EnergyPlus limited the number of output columns to that. Modern versions of Excel no longer have this limitation. I don't know how you are running your EnergyPlus simulations, but EP-Launch for example has an option under View > Options > Miscellaneous where you can check "Allow More Than 250 Columns".
