further update… I installed & activated the “Enable bbPress for Block Themes” plugin as suggested by @robin-w and there was no change wrt the subscribe/unsubscribe functionality. Of note, the forums do function normally, and always have, in my configuration. It’s just the subscribe/unsubscribe function that is broken
just an update on this… I have reached out to HB Themes support (multiple times) regarding this issue and although I received an automated response that they received my message(s), I have yet to hear back from them. So much for a “paid for” product
