Architect 10.2B crashes with vs_util error

Hello

lately I've been having problem with one project where Architect keep crashing while building workspace. I use the options "Build automatically" and "Build before launch" is turned off, but sometimes when I run a program or check syntax message "Building workspace" starts and after some time prowin32.exe app error pops out with vs_util error in description. Also, a message "avm runtime busy" often appears when checking syntax. Thing got little better since I stoped using "Build automatically" but compiling all files still causes a crash. I even created another workspace for this project (deleted .metadata), tried with -clean and everything is still the same. I have another workspace with a codebase that matches this one in 90%, project setting are practically the same. Main difference is that this project is new and it's open on 10.2B while the other one is opened few years ago on 10.1B and migrated through versions. Option -s on project is set by OEA defaluts to 200. Database is started with the project and there is no unusual entries in db log.

This event creates following in Error log:

An internal error occured

How could I find out what's going on with this? Is there any other log beside .log in workspace metadata and where could I find it?
