GST utility 3.2.3 json not generating

Hello everyone,

I have been facing issues since the last update of gst offline utility update (version 3.2.3). I face two issues in this version.

1. While importing excel file, the utility sometimes throws an error about duplicate HSN. I resolve it by simply by deleting the data, closing the utility and restarting the process. (Yes, HSN are duplicate but they have different gst rates, clothing has slab rates 5/18% hence a single HSN will be there in the return two times). 
2. While clicking the "GENERATE FILE" button to generate the json file. The utility just keeps on loading/buffering and never generates the json file. 

The second bug is highly stressful as I have to repeat the whole (import, try to generate, close app, reopen app, delete previous data, import again and then again gets stuck while trying to generate json) process dozens of times to get the json file. 

During my last return filing, I even tried reinstalling the utility and even trying the separate csv file instead of single excel file but it didn't help. 

I also searched on YouTube and found 3-4 similar comments on a few videos but no answer. 

Is anyone else also facing the same issue? If yes, were you able to resolve it, then how?

Please help. 

Regards
