Setting colors does not work in Google Slides with TEXRendr.com backend

I just installed the add-on this morning and at first it worked, but then all of a sudden this bug popped up where color is no longer rendered. It is always black, and my equation is prefixed with "RGB]89,89,89" corresponding with the text color. This appears to be an issue with TEXRendr.com, as similar things happen on their website.

I also noticed that several symbols suddenly look different. It appears to me that CodeCogs is the default renderer and TEXRenr.com the fallback. As it so happens, CodeCogs renewed their SSL certificate today and made a mistake, causing any PNG I want to download from there to trigger a security alert. I assume the same thing happens in Auto-LaTeX, causing it to use the fallback. Since they renewed it just a few hours ago, it makes sense that it worked this morning when I first installed it.

Anyhow, I would appreciate it if colors were made compatible with the TEXRendr.com backend or, at the very least, handled more gracefully.

Start at the Google Slides rendering path and compare the CodeCogs and TEXRendr.com fallback behavior, focusing on color-prefixed equations and symbol rendering. Reproduce the issue with a colored equation while CodeCogs is unavailable, then verify that the fallback preserves colors or handles the renderer failure without malformed output.
