Your guitar's volume knob is the fix.

Turn it down. Not the amp — your guitar. When you’re in a small room with an amp cranked, feedback happens because your pickups are picking up the amp’s sound and re-amplifying it. Rolling back the guitar’s volume a notch breaks that loop without killing your tone.

If that doesn’t work, try pointing your guitar slightly away from the amp or adjusting the amp’s EQ — cut some mids or highs where the feedback frequency lives. A noise gate pedal is a permanent fix but takes setup.
