Blank Action Browser and Variable Viewer

[KiZ]

Hi. I'm using the latest version of Playmaker on Unity 2021.3.27f1. For some reason the action browser doesn't show anything with hundreds of error messages popping up. It's been like this for a while and the only solution I have so far is just reopening unity again and again and try to find luck... Sometimes when I reopen Unity the action browser works, but most of the times after running a while it just goes blank again. The variable browser is also looking weird. I tried reinstalling Playmaker and deleting the Library folder, which neither worked.
Attached are the error messages and how the browsers look
Also I found an old post which seems to have the exact same issue as I have, but still having no clue on how to solve this. https://hutonggames.com/playmakerforum/index.php?topic=24027
Appreciate any help in advance!!

Hi.
are you using some custom actions?

if for example you make a new scene and create a new fsm, does the issue happen there as well?

It looks like a editor ui issue which might be caused by some custom action(s)

i know that with Data Manager, the xml actions have/had issues with the pm UI (at least on PM version 1.9.0)

Hi.

Yes. I downloaded a bunch of actions from ecosystem.(array maker, timeline, tmp...) But I don't have data manager in my project.

The problem with the action browser exists no matter which scene I open. While the issue with the variable viewer happens occasionally, haven't found any pattern yet. The variable viewer looks fine on a complete blank fsm tho.

One recent solution I found is just to run the game, and the action browser would work as intended during run time... so that immediatley after I exit run mode, the action browser would work for a while (then goes blank at some point for no reason.)

So should I delete some custom actions to see if that helps?
