Corrupted installation (Application error: a server-side exception has occurred (see the server logs for more information).)

[Macellatore]

I'm not sure what i was doing (maybe adding another participant to a group, or adding a expense linked to a new participant) but it seems like something went wrong.
Now when trying to access the web ui I get this error:

Application error: a server-side exception has occurred (see the server logs for more information).
Digest: 4178383556

App logs return:

app-1  | PrismaClientUnknownRequestError: 
app-1  | Invalid `prisma.expense.findMany()` invocation:

app-1  | Inconsistent query result: Field participant is required to return data, got `null` instead.

I tried poking around in the db but i can't see anything wrong with it (i'm not a champ with dbs, i can barely move around and query stufff).

Could you help me fix this?

Thanks in advance!
