Car insurance went up $50/month after canceled theft claim

I’ll save the details of the story and give a TLDR version. 1-2 months ago I thought my car had been stolen because it wasn’t in my apartment parking lot. Turns out I had driven it to work the day prior, forgotten I drove (I usually walk/bike), then walked home. My car was safe and sound at my work’s parking garage.

But before I remembered that, I had filed a police report and called my insurance company to file a claim. It was within 2 hours from the time that I did all that that I realized my embarrassing mistake. I called the police to cancel the theft report then called my insurance company to cancel the claim immediately after confirming that was where my car was.

Fast forward to today and I got my bill from my insurance and I see that my policy went up by ~$50/month. Besides this canceled theft claim, I have no other claims or violations for over a decade.

I’m going to call my insurance company to see what’s up. But I would like to get some background knowledge before doing so. Is it likely that this increase is from the theft claim? If it is- is it a mistake since I canceled the claim?
