After update to Jatos 3.8.1.: A problem occurred: Internal JATOS error during [...]

Hi,

I recently updated my local Jatos to the latest version (3.8.1.). Unfortunately, I am running repeatedly into some fatal errors.

First, everything seems to work normal, but after a while whenever I try to start a study, I run into the error message:

A problem occurred:

Internal JATOS error during /publix/[here comes the study code]. Check logs to get more information.

I receive this message for every study that is listed. The only solution seems to be to set up a new Jatos environment, until it crashes again. When I use the "Tests" options under "Administration" everything checks out as "OK".

The log gives me the following output:
