Hello @eharvest. Thanks for reporting. Please specify what exactly You mean under "Add options" - options in "Customizable Options" or only in "Bundle Items" section of the product page.

I'm having this same issue. It seems to occur when the BUNDLE PRODUCT has a large number of options (Doesn't occur with 2-3, but does with 7+).

What he means by "Add Options", refers to the Action Button under the heading "Bundle Items" where you can add items to the Bundle.

This may be solved by increasing the value of max_input_vars. You may do this either in php.ini or in .user.ini in the magento root directory, if you are on a shared platform where you cannot change php.ini

I have the same issue(exactly like @webmdt described - I used 20 options with single products)
I have Magento ver. 2.3.5-p2 and php 7.3. I increased max_input_varr to 100000 but it didn't helped.

Open the console tab in your browser's developer tools and check if a CORS error has occurred. If there is a CORS error, please add the address to the csp white list... This is the most frequent cause in my case.
