Recording stopped then started an hour later ?

Hoping someone can help me out with this.  I started the recording at the beginning of the meeting. We got the standard audio notification that the meeting was being recorded. Then over an hour later the same audio notification came on letting us know the meeting is now being recorded.  There was no notice that the recording stopped.  There was no cohost, only me, and I didn’t stop or pause the recording. There was no internet connection issue.  That hour gap is not recorded. There are two separate recordings, the first 20 minutes and the last 25 minutes.  An hour in between is missing.  What would have caused this issue and how can it be avoided moving forward?  Any assistance with this will be greatly appreciated.
