The file is not large. Only ~2k rows and 462 kb. I've certainly uploaded larger files to QGIS and never had any issues. I've force quit the app and tried to re-add the file, but that hasn't worked. I've started a new project to see if I can add the file by itself, and it still is unresponsive. I've waited for more than an hour and no dialog shows up after this white box. What can I do? Is it a RAM issue? I have more than 20 gb of storage on my machine. It's QGIS 3.10.
