I have seen this was an old problem where if you try to add a Vimeo video to the product page a modal appears with Attention Error: "Video not found". According to Adobe this was fixed from 2.4.3, but I have tried 2.4.5-p1 and 2.4.6 and I get the same error.
I already have Vimeo added to my CSP policies and have tried adding player.vimeo.com to the *.vimeo.com which already exists.
Currently all the product videos that were added in the past work. But, if I click on them now the URL is blank with the error, even though the database contains the correct URLs. Trying to add a new URL gives the same error.

It looks like I managed to fix this by adding an extra policy
<value id="vimeo" type="host">vimeo.com</value>without the wildcard toscript-srcandframe-src.
