error exporting application

I cannot export my app. Whenever I try to make a mistake and I don’t know what else to do. It has already been published on the Play Store.

if is published in playstore then you should use the same keystroke generated in the playstore, else it wont export i think

you can’t export the aia file? which error message do you get?
how many screens does the project have? how many assets? how large is the project?
