Unable to modify a dataset directly in the dashboard

I have a dataset which is unusable, when trying to modify fields, or duplicate or delete data, I have a couple of errors.

This is quite critical because I have the error when directly working in the dataset or when users are in the application.

The support proposed to me different solutions which are not working (try another connection, try another browser, try another PC, etc…)

Here is a list of errors I met:

Does anyone encounter these errors?

In the web developer console on firefox, I see the below message when I got the error:
mutating the [[Prototype]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[Prototype]]

Does anyone know what does it mean?
Many thanks for your help

Did you use code on your site and by any chance tried to access some object.prototype?
Does this error happens only on FireFox or other browsers as well?

Hi Ohad,
Sorry for the delay replying… After WEEKS, I finally found out the problem (which should not be so long to fix)
I had a hook on the database which generates critical slowness (update on a dataset with more 2000 values to check) and then generates lot of different error messages + unavailability of the website

Anyway, I remove the hook, find another way and the problem is now totally fix… OUF !

Thanks
