Issue with MCP Filesystem on Claude Desktop (Mac)

[rodrigopardo21]

I installed the MCP filesystem on my Claude Desktop and it only worked after I installed Node via my terminal, following several attempts since it wouldn't run at first (I'm not a programmer). This was yesterday, but today, when I tried to have Claude summarize a PDF located in the directory where the filesystem works, Claude starts responding but then, after a few seconds, both the question and answer disappear from the chat.
I ask again, and the same thing happens. I asked Claude why this was happening, and it denied that anything was wrong—until I shared a screenshot. Then it said the issue might be with my app, but I reinstalled it and that didn’t help.
What could be causing this?

I'm curious does the same thing happen with other MCP servers, or just the filesystem server?

I also met this situation when I tried to let it summarize the contents of PDF files or image, but it worked with txt files.
