Why is WooCommerce removing categories from the admin?

Question

WordPress

Has anyone encountered a similar glitch?
I create categories in WooCommerce products, but they disappear from the list of categories, although they can be accessed by url.
Reinstalling didn't help.
The theme is standard woocomerce storefront .

Difficult to say since you haven't provided anything... no logs...
Useful links:
If you have the WPML plugin installed - https://wpml.org/forums/topic/product-categories-i. ..

Here, also useful information. Maybe it's not directly related to WC, but to the DB. Check the integrity of the WP database tables.

Also do a simple debug:
Enable wp_debug in wp-config. Correct the mistakes.
In the same place, turn on the recovery mode / check the integrity of the tables of the VI
Disable plugins one by one to avoid conflict
Try changing theme
Update plugins and theme and VI
