Problem with displaying emails content

For some time now I have been using the free version of eMClient. For a few days now, all the emails I have received and read no longer display the content if I open them again some time later. Only the header of the mail is displayed.
This started on 09 January 2023…
On the other hand, in the “mail not read” folder, there is no problem. I can open the mails, read them, close them… but it only displays mails until August 2022.
I am on windows 10 - last update 22H2
with a cumulative update for windows 10 version 22H2 for x64 systems (KB5022282) on 12/01/2023.

Can you help me?
