Issue at project creation | table planningelement missing

Hi
I have an issue when I want to create a new project (I have this problem with version 9.3.5 and 9.4.1). It seems that the planningelement table is missing.

Please find bellow the log:

Many thanks for your help.

English translation done.
Sorry.

best regards

Planningelement is in the table list but when I click on it (phpMydamin), I have this erreor : "#1146 - 'projeqtor.planningelement' doesn't exist."
