Just downloaded and installed new 1.8.13 (ZIP version)

extracted it all as usual but when I started it, about 2 or 3 seconds after the splash screen I got the blue screen with the sad emoji which lasted for about a second before my computer restarted. The blue screed went too fast for me to read the error code.

1.8.9 that I still have installed (due to ATTiny10 ISP code not working after 1.8.9) and it worked fine. But 1.8.13 crashed just about right away. 3 times I repeated.

I deleted, re-downloaded it, extracted it, and tried again. BSoD again.

Windows 10 Pro, just had a clean install of OS and programs a few weeks ago when I retired my old i7 2700k system for a Ryzen 3 3700x system (new mobo, new CPU, new DDR4, and a new SSD that does 5000mb/sec read, Sabrent rocket) as OS and app drive. Existing drives were just for file stuff and not used for running apps.

With BSoD going too fast, I can't tell what error is coming up. I haven't had BSoD before with this new computer and ran fine with games, stress tested with Furmark and Prime95.

I am wondering if a hidden old file from 1.8.12 that I removed for .13 is causing the issue?

I'm sorry to hear you're having troubles with 1.8.13 @wilykat.

In order to exclude the possibility of some issue caused by the previous installation, try running Arduino IDE 1.8.13 in portable mode, by creating a folder named "portable" in the Arduino IDE installation folder. Even if you don't actually want to use portable mode, this can be a useful troubleshooting tool, since it causes the IDE to use only the files from inside the IDE installation folder, rather than accessing the previously installed files under C:\Users{username}\AppData\Local\Arduino15 and your sketchbook folder.

I just tried the portable version, I didn't experience a crash. When I tried the non-portable version, it crashed so it seems like an old file somewhere broke 1.8.13?
