Wordfence broke site health & other functions?

I’ve recently begun experience strange stuff on my site, I started to think I got a gremlin running around.

So I tested site health, and it showed a couple of things to fix, one of them was something about loop error and cron, but as butterfingered I am, I pressed info, so to go back, I pressed the status button, and all I saw was a white page, with current date and time, nothing else.
What ever I tried, nothing helped, and after googling, I found that somebody had issues with wordfence, so I thought, what a heck, I’ll try, so I disabled wordfence, and now it worked again. But the loop error wasn’t in site health any more.. so I turned on wordfence, and site health was blank again.

I’m starting to think wordfence is interfering with something.. Or everything,.
