I was initially using the 64-bit version then it started crashing. First, it crashed whenever expressions/Python was involved. Then, it crashed when I was closing it. This happens in both the 64-bit 3.4 and 3.10 LTR versions.
Even when installed through the OSGEO4W installer, the problem persists.
Also, is it true that with the 32-bit, I'll be using half the RAM?
