My clients keep having issues with freezing on their application.

This is the 6th client in the last 30 days that has reached out to me saying that the application froze. I've reached out in the past but this issue has not been resolved and is affecting my business. 

The issue may be related to your user's browser. Have you tried advising your users to use another browser as well?

Could you let us know if we can send a test submission to the form to test it from our end?

Yes I have tried using different browsers and so have they. Yes you can send a test submission.

I test submitted the form and it worked fine on my end, kindly check my screencast below:

I use google chrome browser to test your form.

I’m not sure where the issue is then. Most of my clients are using Safari, others use chrome, some use their computers and others use their phone to fill out the application.

I am also not able to replicate the issue on my end. If you could share the steps that the affected user has made until he encountered the said error, that would be great. In that way, we could try to reproduce the issue. It will help if they could also provide a screenshot of the error so we could check further.
