B4J Question B4J 8.90 IDE crashes when opening file dialog

[MM2forever]

Hello guys,

I'm suddenly having really strange issues with the B4J 8.90 IDE on Windows 10 (B4A works fine, so I assume any dependencys are okay?)
I have not updated B4J or anything recently, and this morning I wanted to open a project via the "Open..." dialog and it just exited. I could open the project via the file explorer and it ran but simple stuff like doing CTRL + C also closed the IDE immediately.

I tried reinstalling and manually removing the "AppData\Roaming\Anywhere Software\B4J" - folder, but the neccessary .ini file in there was never created again at the first start so the IDE didn't start at all anymore.

How can this happen? How can I reset the IDE settings or initiate something like a "first run" procedure?
I tried starting it with "-log" but the log doesn't really help or show any crash behaviour reported.

The file dialog is a system dialog. If it crashes then the problem is in the dialog itself. Might be related to a previous mapped network drive. Worth restarting the PC.

Hey Erel, thanks for your reply.
Yes, I suspected something like that so I tried a couple of things, including multiple restarts, removing network connection and clearing multiple entrys of registry keys like that:

HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\MuiCache
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\RecentDocs\.b4j
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\TypedPaths

What still bothers me is that its not only the file dialog. Starting a new project also causes the crashing, and the CTRL+C is also a weird source for a crash.
I work with B4J every day, and this came out of nowhere.
Are there any more detailed debug possibilities?
Could any programm I installed have changed a dependency that is now causing this? I also did a Malware scan but I don't find anything suspicious on my computer.

Any help is highly appreciated

There isn't any error message so I can't say more. As I wrote, the file dialog is 100% a system dialog.

There might be more information in Event Viewer.

Thanks Erel, I should have thought of that earlier:

Looks like I need to have a word with my .NET installation!

(I tried the CTRL+C in B4A as well just now and it crashed too btw.)
