Which editor are you using – the new Block editor (Gutenberg), or the Classic editor?
I downloaded the free ‘Health-Check & Troubleshooting’ plug-in. It’s a bit tedious, but once in troubleshooting mode, you slowly enable each of your plug-ins one by one (or three by three, if you are more adventurous). As you click the ‘enable in troubleshooting mode’ for each one, you then switch to a post you are editing/updating. If there error doesn’t appear, you continue to enable additional plug-ins gradually and keep switching back to editing/ updating mode to check it’s effect. You will eventually enable the plug-in or plug-ins that are causing the error, as the error will reappear when you switch back to the post you are updating. Disable or deactivate the plug-in(s) responsible. Once done, you can then exit troubleshooting mode, and the error shouldn’t occur.
