Crash when clicking "Manage and install plugins" - Fresh install

Affected QGIS version: 3.0.0

I have a fresh install of QGIS 3, installed using OSGEO4W. At the first launch, I choose to not import the parameters from QGIS 2, but rather start from scratch. I also have QGIS 2.18.17 LTS version, installed also with OSGEO4W.

The first thing I tried after launching QGIS 3 was "Plugin->Manage and Install plugins", which produces the following crash:

Crash ID: bcb24f74188137f76f4617168058fc0609bfe2e8

Not sure if it will help, but there is a hope. Could you please try to delete any existing *.pyc files from

C:\OSGeo4W64\apps\qgis

and, just in case, from the current profile folder (you'll find it in menu Settings -> User profiles -> Open Active Profile Folder)

I have the same results after removing all the .pyc files from the C:\OSGeo4W64\apps\qgis and profile folders.

As an additional info, I can briefly see the "Fetching components" windows before it crashes.

Thanks. Anyway, I suspect it's a kind of conflict in your OSGeo4W. Today we notice numerous problems after upgrade in OSGeo4W, while I didn't hear about such problems with the standalone installer (what is basically a fresh installation of packages taken from OsGeo4W)

So I'd try a fresh install (e.g. the standalone installer) first. If it works, probably removing and re-installing all C:\OSGeo4W will help too.

Did you try the qgis-dev (3.1) package, like in the other report? Or the standalone installer?

Looks like a Python crash when the Plugin Manager calls it to fetch new plugins. The question is if the reason is some obsolete files in C:\OsGeo4W, a conflict with another Python instance or just some registry settings.

I just installed QGIS nightly dev with OSGEO4W: no more crash.

It seems to be not reproducable. It may be fixed in current installer, and I believe methods from #26152 could help here.
