Cannot Record

I have tried Dozens of times to record in Audacity and the Same thing happens Every time. After about 25 or more seconds it STOPS recording.
This is happening EVERY TIME. Does anybody know what is going on here ? I uninstalled Audacity and reinstalled it to NO AVAIL.
This is Audacity 2.2.1 Thank You.

How consistent is the time before stopping? Is it always very close to 25 seconds or does it vary a lot?

What precisely happens when it “stops”?

What are you recording? What equipment are you using?
