FsLogix: error.cpp(13): [WCODE:00003b01]

Gianluca Melis 101 Reputation points

This is the third time it happens.
It works flawlessly for a whole week and then it just throws this error and then a bunch of errors follows:


It looks like the error.cpp(13) triggers those "WTSQueryUserToken" and "openVirtualDisk" errors.
OpenVirtualDisk also behaves quite oddly: at first it says "file not found" and then changes to "Filetype not spported".
Is there a way to see what file are those errors referring to??
this persists until i restart the rds.
I have 2 rds with the same exact config, last week the same exact thing happened on both (with +-1 hour of difference), this time the other server stayed clean and didn't throw any error.

I have no idea where to look for!

a downgrade to FsLogix 2004 (2.9.7349.30108) fixed the whole thing.

    this link https://learn.microsoft.com/en-us/answers/questions/259063/fslogixs-crash-errorcpp13-high-availability-filese.html does not apply to my case.
    this one https://www.meinekleinefarm.net/caution-fslogix-2009-2-9-7621-30127-profiles-wont-logoff-completely/ was my first attempt fixing it. I had those groups set locally and i set them via gpo after reading it. it was working fine until last week..

    what is even the error.cpp(13) referring to? I cant seem to find it in any documentation.
    I am also willing to provide logs or any more information if needed.
