After deploying the on render.com, I noticed that the app crashes when refreshing. I checked the one you deployed as well and it has the same issue. I thought it is because of render's free plan and deployed it to netlify but the issue persisted. I believe the issue is because of routes but I couldn't figure it out. Do you mind taking a look at it? And it is really weird because it only happens after it is deployed - it is fine when ran locally.
