multiple links on google point towards two common solutions/factors: Windows defender being disabled fixes the supposed lag/slowness of explorer overall, and using the 'refresh my PC' feature fixes the crashing entirely. Though from what I read using the refresh my PC option uninstalls programs or something to that extent, so backing up may be necessary. I don't know if you've already tried this stuff or not though.
