While loading into multiplayer world minecraft crashes completely due to an exception from Psi.

It appears that it is trying to create a directory but my install is not being made to my %AppData% location and this is causing errors.

Unexpected error

java.lang.RuntimeException: Couldn't create home directory!

crash-2019-04-27_15.16.34-client.txt

I found an issue in my %AppData% folder and am trying again. Will update should it resolve.

Any update on the situation? Does it still crash?

Same problem here:
crash-2019-05-24_23.43.15-client.txt

Edit: After further testing, it seems like psi and autoRegLib are not the source of the problem. I have played with psi-r1.1-72 and autoRegLib-1.3-26 in two mod-packs without any problem, but when I try to load world with them enabled today the game crashed. My guess now is that the crash has something to do with the newer forge-14.23.5.2838; I am playing on a mac so file system permission could also be causing this problem.

Edit#2: whatever the actually source of crash is, it seems like the persistent progression feature (to keep your psi progression across worlds) triggers it, and setting "Persistent Data" in config to false will stop the crash

Can confirm @Heaper327's solution works. Also, I got this crash right after migrating my mods/ and config/ directories to a fresh modded install. I wonder if it has something to do with a file or directory suddenly disappearing unexpectedly, somewhere in the .minecraft.

Closing this as no relevant reports have come and seeing as Psi ditched this in 1.15.
