Incompatibility problem from version 4

Good morning.
I have a website that I have been using for a long time, The Post Grid. I never had any problems, until I upgraded to version 4.
I use to analyze the behavior of plugins and loading times, which is called Code Profiler. Since The post Grid was updated, when I want to launch the Profiler, it returns the following error:

12-May-22 13:21:04 ERROR The website returned the following HTTP status code: 500 Internal Server Error. By default, the profiler will always abort and throw an error if the server did not return a 200 HTTP status code. You can change that behaviour in the Settings section if the page you are profiling needs to return a different code (3xx, 4xx or 5xx).

(The parts of the log that are with several successive asterisks, it was my replacement, since data from my website appeared that may be sensitive)
I’ve already contacted the Code Profiler team about this issue, but since this is clearly an issue stemming from The Post Grid, they strongly encouraged me to contact you.
Could you help me to solve this problem? As I said before, everything was working great until your application was updated to version 4.x. I have all the plugins updated and I don’t want to do without any of the two applications mentioned in this message. I also clarify that the 500 error is not real, since my website never suffered a crash, and continues to function normally.

Thanks in advance. And I await your prompt response.
