App stopped working on cloud out of nowhere

Hi everyone!
My app was working, but out of nowhere I got an error today and shows an error:

ImportError: /usr/lib/x86_64-linux-gnu/ version `GLIBCXX_3.4.29' not found (required by /home/appuser/venv/lib/python3.9/site-packages/kiwisolver/

Do you know, how could I fix it? I would really appreciate your help!

Hi @stepdasha, can you share your app code/a link to the app?

Thank you for your reply @Caroline ! this is the link

And this is the GitHub page GitHub - stepdasha/spike

I just followed your app link and entered all the suggested example numbers and it appears to work. Perhaps something got updated and it just needed a reboot? Are you still seeing a problem?
