After upgrading to 2025 R2 Build 25.201.0213.3, we encountered a very strange issue.
Within one day right after the upgrade, we accidentally found that clicking the Inventory ID in the sales order details grid had no response and triggered no error and no pop-up window displayed.
We spent a lot of time troubleshooting and conducting tests in the test environment, which has been upgraded for two months and works properly.

When we were at a loss, the function suddenly and miraculously returned to normal today. Clicking the Inventory ID now brings up the pop-up window as expected.
We did not update the browser (both Chrome and Edge showed the same issue in previous tests), nor did we modify any line of customization code. The problem got fixed automatically out of nowhere, which is extremely weird.
Does anyone know the root cause?
