Unable to see published Podcasts

First, the published episodes stopped appearing on the platform; at most, only 2 appear randomly, which is strange because everything was published. I tried refreshing, but it didn’t help much. I decided to archive the podcast and then unarchive it in an attempt to get everything back to normal, but now I can’t republish it because it says that the artwork doesn’t meet the guidelines... but the artwork disappeared, and I can't replace it (the small window to make the change won't open).
