Rank Math Plugin and Query Monitor conflicts.

[ldiazZB]

We are trying to implement Rank Math on our site. Our site has around 10,000 pages ( including posts and other taxonomies). We tried to reduce the number of posts on each sitemap, which currently is 200. It generates like 48 sitemaps. When we tried to visit each we got the following error, this error repeats around 10k in our logs files. Causing the site crashing therefore google can’t read this sitemap.

We tried updating WordPress, RankMath, and RankMath Pro, but nothing worked.
Also, we disable all the plugins and the only one that give us conflict was Query Monitor.

Below you can find one of the recent errors. This error caused our site to crash because repeats around 10k in our logs.
We are already communicating with Rank Math, they told us that maybe something with Query Monitor is causing the problem.

Behold, the most common response from plugin support ("not our problem"). 👎

@ldiazZB Are you able to get a full stack trace for that PHP error? I don't think it's coming directly from Query Monitor but I can't be sure.

@johnbillion They appear when I have Query Monitor activated and visit /sitemap_index.xml from Rank Math.
