Happens just sometimes.

I'm assuming it's page level progress oriented.

Starting here at onCompletionChange https://github.com/adaptlearning/adapt-contrib-pageLevelProgress/blob/9c6ec1584d965bdf8517ad3699b043d5812a8a01/js/adapt-contrib-pageLevelProgress.js#L64-L77

Then erroring here https://github.com/adaptlearning/adapt-contrib-pageLevelProgress/blob/9c6ec1584d965bdf8517ad3699b043d5812a8a01/js/completionCalculations.js#L20

There is a pull request for a similar bug which you could try, if you're able.
https://github.com/adaptlearning/adapt-contrib-pageLevelProgress/pull/236/files

Note: In future, when reporting console logs, you need to have first turned on Source Maps in your project settings so that we have source code numbers instead of adapt.min.js:1. adapt.min.js:1 means "line 1 of the minified production code", which is a problem, because everything is line 1 in the minified production code.

Thank you Oliver. I will try that. I think it will fix it.
