Frigidaire Washer - Loud noise during spin cycle

I have a Frigidaire washer (Model GLWS1339CS1) that suddenly started making a very loud screaching noise during the spin cycle. Any suggestions as to what it might be? Belt? Idler pulley? Tub bearing?

Thank you in advance for your help!

The washer has stopped making the loud noise. In total, it made the noise during two spin cycles and hasn’t done it since. We’ve done approximately 6 loads of laundry since the noise stopped with no problems.

Baffling
