What was the impact of the 2019 Korea-Japan trade dispute?

So in 2019, this happened.

TL;DR Then prime minister Shinzo Abe (RIP) had a seemingly (according to his autobiography) deeply personal issue with then Korean president Moon Jae-In over some historical issues. This led to Japan restricting the sales of certain semiconductor related products to Korea. Korea attempted to mitigate said issue by trying to localize production and saw some success.

Either case the issue was pretty soon overshadowed by the Covid fiasco, Shinzo Abe leaving office, and Korea had a new president. The new leaders quietly dropped the issue since it was clearly helping nobody. Both sides claimed victory.

Overall it wasn't the biggest dispute, but had it not been disrupted by COVID, I wonder if Japan and Korea had the ability to seriously damage each others economies. What was the worst case scenario here?
