Should be truthful about my one month termination?

Worked at a company for only one month. It was an entry level role and I seriously thought I was smashing it.

Before joining the company I could see that it was already pretty toxic. Asked to start on an earlier date than agreed on at least 3 occasions(I would have breached my contract with previous employer if I did), changed contracted hours from job ad and an awkward moment as the interviewers were married and had a little disagreement during the interview.

I did tasks that were not in my job role. Only had 2 weeks of onboarding and the rest of the time I was pretty much left on my own. Everyone was on holiday for the last 2 weeks so say I covered their work as much as I could(probably not great because it a completely new role). It was very fast paced role but I tried to be as proactive as possible. I would literally rush to the toilet and rush back lol. The workload was insane and overwhelming.

Im looking for a new role to get back on my feet. What do I tell interviewer?
