A regression in September 2020 CU for for SharePoint 2019 was identified.
Users who install SharePoint in non-english language or install non-english language packs can’t work with some modern pages in non-english sites.
To work around this issue, international users can switch back to classic mode.

Can you confirm me that we are not affected by this issue if we have install Sharepoint in English version with multiple Language Pack (like french one) ?
This patch corrects some CRITICAL Vulnerabilities and Exposures and we should absolutely patch our Sharepoint server ASAP. (2013-2016-2019) .
If we are affected by this regression , what is your advice? The workaround is absolutely not possible in our context
Thks in advance
