Hi BOFHJunior,
Thank you for reaching out, and sorry for the inconvenience.
I have carefully checked the issue, and it occurs in the frontend editor when table items are not evenly distributed with pagination.
For example, if the table contains 10 elements and pagination is set to 3, the issue occurs (since 10 ÷ 3 leaves a remainder of 1). However, if there are 9 elements (9 ÷ 3 = remainder 0), the page builder does not crash.
I have reported this issue to the development team, and hopefully, it will be resolved soon. However, the preview for the frontend works fine.
Please feel free to reach out if you have any further questions.
Best regards
