I have the exact same issue. The button doesn't solve the problem.
Also, since about the same time this started appearing, I no longer see stock value on the dashboard (0€ instead of the value.) Might be unrelated, and I will try to use some of the ATUM tools so see if it helps, but so far no luck (for example, updating the calculated fields doesn't help).
WordPress versie 7.0.2
Actief thema: Twenty Twenty-Five (versie 1.5)
Huidige plugin: ATUM Inventory Management for WooCommerce (versie 2.0.2)
PHP versie 8.2.32
