Upload to App Store Connect internal gets stuck almost every time

About 90% of the time I attempt to upload my app build to App Store Connect 'Internal Testing Only', it gets stuck on either "Sending SPI Analysis to App Store Connect" or "Waiting for App Store Connect SPI Analysis Response". The only solution I've seen is to sign in and out of my dev account in Xcode and close the app - and keep repeating this process until it works again. Sometimes it takes one, sometimes it still won't work after doing this 10 times. I learned that I can export the IPA and upload via Transporter which I have been doing recently. But this is an extremely annoying problem that I do not understand why it continues to happen every session, and I have seen barely any other forums anywhere with this same issue. Can anyone help?
