obsidian-tasks: Query stuck on "Loading Tasks"

The very first time I tried displaying queries on my phone, I got a message that Obsidian was indexing my new files. Afterwards, the process of loading my task queries was rather slow, and I could see the result window being populated with one new task per second. I have about 3000 files, of which 300 are tasks (I use 1 file per task). I thought I could speed things up by making sure my queries only referred to the folder which stores my task files, so I added ‘path includes tasks’. However, now ‘Loading tasks’ just goes on forever, and nothing happens. Just to verify how quick things are on my laptop, and restarted Obsidian, and now the queries are stuck there too…

I’m syncing my entire vault using Syncthing. First I thought there could be some issues related to both devices using the same cache files, but in my .obsidian directory, I’m not finding anything that looks like a cache…

The page I’m loading has the following queries

### Tasks

path includes tasks
