Hi @m8nix. Thanks for your report. The Arduino IDE developers are tracking this bug here:

IDE fails to open on a RAM drive, stalls at white window and busy spinner

opened 06:32AM - 21 Jul 22 UTC

topic: code type: imperfection

### Describe the problem Win 11 with MSI install or UnZip to empty folder sta…rts main window with title bar. Splash persists and main window with no menu just persists until closed with spinning wait animation. This will persist for hours without change or status feedback other than the spinning wait animation. Machine has been restarted as needed to allow removal of indicated folders and behavior persists. ### To reproduce Unzip arduino-ide_2.0.0-rc9_Windows_64bit.zip to empty folder. > ZIP is 'unblocked' so extracted files not marked 'Blocked' > Folder is in an excluded 'scan' folder for MalwareBytes > Windows Defender also active, added exclusion, no difference Install arduino-ide_2.0.0-rc9_Windows_64bit.msi > completes and exits with no notice, but found installed Execute and noted behavior persists Attempts to resolve noted here https://forum.pjrc.com/threads/53548-Arduino-CLI-And-IDE-2-RC-Release-Teensy-Support?p=309665&viewfull=1#post309665 > That is post arduino/arduino-ide#270 , minor update on p#274 prior to creation of this issue. Removed `%appdata%` folder `local\arduino15` and the two in `roaming` and no difference. ### Expected behavior Expected either the IDE to appear like early nightly builds did Jan/Feb, or present some error messages or feedback as to the nature of some problem with startup. ### Arduino IDE version #### Original report IDE 2.0 RC9 #### Last verified with 76f9f635d8558f399423f64c0c709e3a53bdcd03 ([reference](https://forum.arduino.cc/t/arduino-ide-2-stalls-on-start/1037599/13)) ### Operating system Windows ### Operating system version Windows 11 : Microsoft Windows [Version 10.0.22000.739] ### Additional context Scanned open issues across 8 pages and not seeing notes of anything active and related. Ran nightly build before RC9 release with same results as found with new RC9 release. >Posts prior to RC9 with nightly builds and efforts to resolve in this thread: https://forum.pjrc.com/threads/70455-Teensyduino-1-57-Beta-3?p=309464&viewfull=1#post309464 { posts arduino/arduino-ide#33,36, 38 I can post any `.log` files that may reside or help understand what is hanging this system startup. Not aware of anything else that may be present on the system causing this. Running the EXE from the ZIP in an ADMIN command box I get this: ```text C:\T_Drive\ardIDE_2>"Arduino IDE.exe" C:\T_Drive\ardIDE_2> Starting backend process.
