[SOLVED] codium + pcmanfm-qt == 70+ CWD and SIZE commands per second

Local: Kubuntu 21.10, VSCodium 1.65.2, PCManFM-qt 0.17.0

Server: Windows Server 2016, FileZilla FTP Server

I use VSCodium (the MS telemetry free version of Visual Studio Code) as my editor, PCManFM-qt as my FTP client. It's a great combination because PCManFM doesn't prompt me to upload and overwrite remote files. Watching my FTP server in real time, the logs are as expected when I open PCManFM. It's fine when I open VSCodium with no open files. However, if I open a file from my server using PCManFM in VSCodium, one of those two programs starts bombarding my server with CWD and SIZE requests:

What sticks out to me are "bower_components" and "node_modules." Up to seventy per second. That's okay for a while, but then it starts to interfere with saving files and I get codium and PCManFM both as processes I can't kill.

I don't use github, subversion, bitbucket.
node is installed, but I've never used it that I know of, and I can't figure out how to remove it, or even if I should.
bower is not installed.
I've disabled all VSCodium extensions.
I've tried every combination of Dolphin, PCManFM, VSCodium, Kate, and Visual Studio Code.
ADDITIONAL INFO: this only happens with .js files. Once a .js file is opened, the server starts getting hit. Closing the .js file doesn't stop the behavior. Only closing VSCode stops it - if I do it before it locks up.

This behavior doesn't happen with Dolphin. It doesn't happen with Kate or Visual Studio Code, with .html/.css/.asp/.json files. Only the combination of VSCodium and PCManFM-QT and javascript files. I don't even know how to begin tracking down this issue.

The end goal is to stop the server bombardment and retain the use of VSCodium and PCManFM-QT if possible. Help!
