What are the exact steps in details to reproduce the issue? I have logged in to an account and I don't know what to do next:

[ThomasCarnt]

Click contacts in the top left and change to deals - click create deal in top right - fill out deal on flyout window and click create at the bottom.
You should then get the below error message

[stephenhawk8054]

click create at the bottom.

How does the create button/section look like?

[ThomasCarnt]

You fill out a form with different info to create a deal and link it to a customer or company

Absolutely fine if you don't have that, you can click the orange create regardless and it should give you the error

I don't see any breakages after clicking on the orange Create button

Thank you for the video.
The issue is very intermittent for us when using ublock but works every time when disabled.

Another place where elements do not load are under that "edit this form" hyperlink in your video in the top right of the flyout window

After clicking that,
The left hand side should have properties listed and just continues to load while the number of blocked elements goes up slowly

Integrated app within our Hubspot domain was causing this interaction with Ublock. Linked to tracking and form completion.
