How to fix a compile error related to Google Tag Manager on my site?

[BedBuddies]

Im getting a compile error that randomly comes up instead of webpages on my site.

I was originally getting three errors and they were all related to google tag manager.

I went into my google analytics preferences section and removed the old UA script as Im now using GA4 and its removed two of the compile errors.  The error below is the remaining one, and Im not sure where to find it to remove it from the code?

Compiled with problems:
