SBIE2313 SBIE2204 SBIE2305 could not invoke program 346

Win 10 21H1 home. i7 7700k 32RAM

unimportant background story: After fresh reinstall and update windows 10 i installed sandboxie plus 0.7.5. (Tried 0.8.2 too, and classic 5.49.x / 5.50.2) I took lucky On first try to start steam in sand. But it was the only one sucess try. Next attempts to start in sand to some programm failed. Reinstallations didn't help. In classic ver. after choise a path selection to app I was getting the error 346. In plus ver. I could no longer even choose the path to the program. I had received errors: SBIE2313 Could not execute SandboxieDcomLaunch.exe SBIE2204 Cannot start sandboxed service DcomLaunch. There are no programs in any way conflicting with the sandboxie, because this is a freshly installed Windows.

there are references to these errors on the Internet, but their solutions did not help me.

On my own I found what, as it seems to me, could be the reason for these errors. Probably the problem with these errors is the exploit guard feature in Windows Defender. I managed to get around these errors by adding start.exe and SandboxieRpcSs.exe in exploit protection -> programm setting ("ACG" - on).

Now I am getting error "SBIE2305 out of memory". There are no working solutions to this problem on the internet. I tried to add other exe files to the exploit guard, select other checkboxes. Increased allocated memory in advanced system parameters. Installed Windows sanndbox on the home version from https://www.deskmodder.de/blog/2019/04/20/windows-10-home-windows-sandbox-installieren-und-nutzen/

The last time, after reinstalling the sandboxie on the classic version, I managed to select the program and run it in the sand. But it is incomprehensible because of what. i still have sbie 2305.

I am writing this post so that the developer can see and understand in more detail how exactly the exploit guard affects the sandboxie and help in solving Sbie 2305.
