FPS decreases over time in editor (Potential memory leak?)

Question

Ever since updating to the newest version of Unity, I've encountered a problem of some (not all) of my projects, even ones made since updating; my FPS in the editor starts at about 300 FPS; it then decreases (usually within 5-10 minutes of opening the editor) more and more, until the program inevitably crashes. I made a new project, with the only asset being the Invector Third Person Controller, yet it still happens; I'm guessing the problem is some kind of memory leak, but I cannot pinpoint the problem.

Any help would be appreciated; thanks!

Open up Profiler window and switch Playmode to monitoring Editor itself. There is all the data you need to diagnose the issue (memory allocations included)

I did that; it showed a ton of the "Others" category, what could that mean?

Btw I checked the memory usage, it seemed fairly normal (400-500 $$anonymous$$B used by the app).

If Unity Editor uses 500$$anonymous$$B at the moment when it crashes then it not a memory leak issue but something different. First things first, I recommend updating to 2019.3.15f1 (just to be sure it's not a bug fixed already)
