Where is a mistake in this code, which raises ValueError? - matplotlib

Question

I have a code:
fig, ax = plt.subplots(figsize=(5,8))
ax.barh(top20_deathtoll['Country_Other'], top20_deathtoll['Total_Deaths'], color='red', linewidth=0.45)
ax.set_xlabel('Total Deaths', fontsize=10)
ax.set_ylabel('Country', fontsize=10)
ax.set_title('Top 20 Countries by Total Deaths', fontsize=12)
ax.spines['top'].set_visible(False)
ax.spines['right'].set_visible(False)
ax.spines['bottom'].set_visible(False)
ax.spines['left'].set_visible(False)
ax.tick_params(left=False, bottom=False, labelleft=True, labelbottom=True)
ax.xaxis.set_ticks([0, 150000, 300000])
ax.xaxis.set_tick_params(labelbottom=False, labeltop=True, color='grey')
plt.title("The Death Toll Worldwide Is 1.5M+", x=-80000, y=23.5, fontsize=17, fontweight="bold")
plt.tight_layout()
plt.show()
When I run following code it raises a value error:
ValueError: Image size of 22320474x10268 pixels is too large. It must be less than 2^16 in each direction.
I wonder what image is mentioned in traceback and what can I do to fix it.
EDIT
Here is the first part of traceback, I can't post all of it baceause then there's too much code in my question. I hope this will be enough, forgive me if I didn't understand something obvious cause I'm a quite newbie:
