Buffer Error/Faulty “apply_builder_in_content” Hook?

Hi,

I recently found and deleted the debug.log as it was 12,8GBs (!!!). Debugging is turned off in wp-config.php, yet regardless it was regenerated and just a day later it was already about 190MBs.

The log is way too long for me to paste it here (also Pastebin got hung multiple times when i tried to paste it there), so I will try to paste only the beginning, which seems to be the most crucial part, as the rest of the log is just echoing my website’s structure. It would be great if someone could help me pinpoint the error. Thanks for your time already in advance!

The first few lines of the log:
