OK, good news, got it!
After following @jrmcfly 's instructions for getting all the addons disabled I started enabling them in small batches. The trick (learned the hard way...) is to enable an addon, then exit Kodi and restart it. The issue kicks-in ONLY after restarting the entire app, not immediately after enabling the addon.
With a bit of patience eventually I arrived at the culprit: it's "Artist Slideshow". I will report this case on the addon thread here, which actually contains a similar recent case but on a RaspPI.
For the time being, I can live without it.
