this will be presumably related to symlink isolation,
try adding FuncSkipHook=NtOpenSymbolicLinkObject to your sandboxie ini
if that works you will need to find out which symlink is causing the issue using the trace monitor
and add
ReadIpcPath=the_symlink_path_you_found
please note there may be more than one required symlink object

added it here and still getting the error, Its extremly upsetting cause it worked a week ago.. then i got the issue for a short while updated sandboxie and it worked for a day.. reinstalling sandboixe doesnt fix it.
Uninstalling sophos also did not fix it.

It should not be added under [UserSettings_XXXXXXXX], but under the sandbox in question.

I did try that too, should have mentioned that..

Get the same error when i put it there

Then please check older builds and tell us in which exact build the issue was introduced

Also you could try ReadIpcPath=$:*

tried that 2nd and did not work
I uninstalled past 2-3 weeks of windows updates and now it works.. so one of them broke it it seems.

if needed i can reinstall them 1 by 1 until it breaks.

yes please try that,
if you have KB5014019 please try this one first

you may also try setting
EnableWin32kHooks=n
but this requirers the driver to be re loaded or a reboot

Reinstalled all except KB5014019 and it still works so seems that broke it, am going to reinstall it and then try to disable the thing you mentioned.

Update it works on KB5014019 if i set it =n.
Both Epic games launcher and the game in steam launch now :)

Ok there seam to be some issue with win32k hooks and some recent changes in windows, hence please mark all issues that can be resolved by disabling that feature with the win32k label.
Not sure how to proceede from here this feature was to fix a particular edge issue.
I think i will make it disabled by default again and only be on by default for edge.
