Error decoding JSON data: Control character error, possibly incorrectly encoded

Hi there,

I am using system plugin HeadTag 3.5.10 on Joomla 3.9.26.

Using it to add about 100 hreflang custom tags for menu items.
When I am about 130+ tags down, the whole website stops working & this error appears:
An error has occurred. Error decoding JSON data: Control character error, possibly incorrectly encoded.

My hreflang tags are very basic, nothing fancy and very consistent for all the menu items.
Is there a cap on how many custom tags I can add?
Any advice on how to solve this?
I await your soonest reply. Thank you for your time.
