Bolt - (Mac) Cannot open two instances of the fuzzy window at once.

kodagames · July 25, 2020, 1:20pm

I’ve just downloaded Bolt 1 from the asset store and I have an Invalid operation exception: Cannot open two instances of the fuzzy window at once. This makes bolt unusable on a Mac. Any ideas on how to resolve this? I’m using an iMac to develop and the latest version of unity 2020.1 if that helps?

Also would it be possible in the future to dedicate a forum section to Bolt or visual scripting?

Below is the full error:

Same here (MacOS, Unity 2020.1.0), Bolt is just not working, throws the “InvalidOperationException: Cannot open two instances of the fuzzy window at once” error every time I try to add a node on a Flow Graph. Also, when I create a variable, I can name it but cannot chose the var type (“Inspector block metadata mismatch” error).

mltlsk · July 25, 2020, 6:48pm

jup. same here. also tried to reinstall in another project. same problem

used Bolt and Bolt Kit: Platformer Tutorial Assets

getoffworld · July 25, 2020, 9:40pm

Same here. Mac running 2020.1 and Bolt 1.4.12. 999+ errors and can’t add any Units to the Flow Graph. Bolt is essentially dead. All the old graphs I created before it decided to stop working operate fine.

kodagames · July 25, 2020, 11:33pm

I’ve tried bolt on a borrowed PC and everything seems fine (Unity 2020.1), seems like a bolt/Mac issue looking forward to a solution to get back to my trusty Mac =)

Utroman · July 26, 2020, 2:45am

I have been experiencing this as well.
I attached a FlowGraph to my cube, opened the graph and this error shows up when I right-click in the empty grid space or press Cmd-E

Has Bolt given up support for the Mac since this May or are their compatibility issues with Unity 2020.1.0f1 and Mac OSX?

mangoteeth · July 27, 2020, 12:13am

I can also validate this issue on OS X 10.15.6 running 2020.1.0f1 Personal
Was really looking forward to digging into this!

sahilsimransingh100 · July 29, 2020, 3:50am

same here mate

ekscom · July 29, 2020, 6:46am

Same, but on Win7.
It’s all Rohit’s fault! Get 'im!

pilz3d · July 29, 2020, 9:30am

same problem here

maglat · July 30, 2020, 10:38am

Any news on a fix? Still have the issue on Mac with Unity 2020.1.0f1

i think the issues is with the hardcoded path which cause the issue on mac

Ludiq.GraphWindow.OnGUI () (at **C:/**Users/…

On mac there aren’t hard drive letters

kakubeiUK · July 31, 2020, 12:18pm

This is awful. There is a 2 month old post here: https://support.ludiq.io/communities/41/topics/5241-cannot-open-two-instances-of-the-fuzzy-window-at-once

Saying the fix will be out in the next release.

Surely a quick patch by Unity is needed. This means Bolt is unusable by any Mac users!

nicholasstephan · July 31, 2020, 4:31pm

Same problem here. Definitely a Unitity 2020.1.0f1 issue. Bolt works fine on Unity 2019.

kodagames · July 31, 2020, 6:28pm

That’s good to know Im going to try 2019 then Thank you!
Confirmed Unity 2019 works, greatly appreciated!

jayluvsdivn · August 2, 2020, 12:05am

I am having the same error appear on windows 10 unity 2020.1.0f1, although Bolt appears to still be working fine for me? would be nice to know what is causing the issue though so this error doesn’t appear every time I open my project

Kneawah · August 2, 2020, 11:01pm

Same issue on 2020. Tried 2019 and not working either.

decoy98 · August 5, 2020, 5:33am

Just confirmed that it works on 2019.3.5 but not 2020.1.0.

Cryoxe · August 5, 2020, 2:35pm

same, Bolt don’t work in 2020.1.0f1…

lfotdg · August 6, 2020, 8:15am

Same here. Going to try 2019. Hope it will work.

JohnC_Unity · August 7, 2020, 8:11pm

Hey folks, sorry you’re all having issues.

We are aware of the issue and are looking into it. You can see further details here

This issue is reproducible with: 2020.1.0a21, 2020.1.0b15, 2020.2.0a17 (1.4.12)
and not reproducible with: 2018.4.24f1, 2019.4.3f1 (1.4.12)

I know it’s not a fix as yet but I hope it helps somewhat.

Thanks a lot for reporting.
