#2109 Build commands randomly stop working

[GrayFace]

I've been using TeXstudio for a couple of days and the problem happened twice. Maybe it happened upon opening TeXstudio, maybe upon closing documents and opening a different one. Some build command stops working, TeXstudio saying it cannot execute the command (first time it happened to Compile & View and maybe Compile, second time to View). Then in options in Build tab I see default commands with standard names, but in the drop-down lists I see txs:// commands. When I select the appropriate txs:// command, the command starts working. Then (probably after a restart of TeXstudio) when I open options the commands in drop-down menus have their normal names again.
I'm using a portable version of TeXstudio (not from Program Files, UAC is disabled).

Which version of TXS? Are you switching between the simplified and the advanced configuration?

[GrayFace]

I've updated since then. It must have been the up-to-date release version. I don't remember switching between configurations. Do you mean "Show Advanced Options" in Options?
The bug didn't happen again since then.

There's been a bug that could cause to overwrite the command definitions in one of the more recent versions. This had been fixed in the current release.

I assume, you've encountered this. Please report back if it happens again.
