Re: MPLABX 5.10 Navigator Windows Does NOT SHOW Anything
Did you delete the whole cache directory, the 'var' and everything in it? I think the whole things needs to go, or just rename it.
If you did, then when you uninstalled did you also remove the user directory (location shown as for the cache directory above)? If not, quit MPLAB and just rename the directory, as this will reset the environment to default with no settings, plugins etc. Restart MPLAB and did that fix it? If not, put the directory back and no harm done.
Normally the reparse works, or wiping out the cache directory is needed if I've had lots of projects open.
