My Arduino IDE (ver 1.8.12 on Win10) crashes when I launch it. Running the arduino_debug.exe I get this error message.
arduino_debug.exe
C:\\Program Files (x86)\\
It also happens on Manjaro linux. In my case removing the folder .arduino15 solves the issue, but I have to remove it every time I open arduino IDE
rm -rf ~/.arduino15/
Win10 folder location:
%HOMEPATH%\AppData\Local
