Unable to dismiss a sync error and reindex the sync

Hi

I have added on PC A 2 files which are ending with .aac, they were uploaded, than the ransomware protection did trigger for unknown reason, even these 2 files were valid.
Then I clicked on bypass these files but the client on PC a still run into errors until I renamed the files on the name part and not the extension part. So that was okay, however on PC B the Client somehow still is getting the old name from the server ans is running in an error loop, I can’t dismiss it and is not copying the renamed files either.
How can I fix that?
The Client is 3.4.2 and the server 24.0.4
