I'm not sure of the cause, and I'm not sure why my log also has those characters.

When I open your ProjectManager.log, I see this:

However, When I originally opened mine up, it looked like this:

But this morning, when I look at the same file, it looked like this:

I don't understand why they look different now, but in any event, since the files still run fine on my end, I don't think that is the cause. I would guess it has something to do with mine still runs from 2019 and not 22
