Addons list freezing the game up on 1.14

[Choicerer]

I can install add-ons, but if I spend more than 3 seconds in the add-ons menu, my game freezes, and this happens both on Steam and in an Ubuntu version I compiled myself. This is the error I get in my console:
libpng warning: pHYs: CRC error
It repeats indefinitely and I'm forced to ctrl+c.
Running Bodhi Linux 64-bit, an Ubuntu based distro.
And here's my full build report:

Can you check the add-ons list again?

[Choicerer]

It's working, fabulous! What did you do?

[Choicerer]

I spoke too soon. It's back.

I have identified part of the issue, we’ll be keeping an eye on this.
