MailClient.exe - System Error

After install eM Client 9.1.2109.0 the client opens but shows error.

When I close the error warning, the client is closing.
What shall I do to fix it?

MailClient.exe - System Error
Exception Processing Message Oxc0000005 Parameters Ox75414CEC
Ox75414CEC Ox75414CEC Ox75414CEC


But if I let the error warning open , eM Client 9.1.2109.0 works fine,
I receive, can send and delete e-mails.
I did a reinstall, same situation…
