PF3 is crashing each time I hit the "Connect to FS" button. I'm using MSFS2020. When aircraft is loaded, I put in the flight plan and then start PF3. Select and load flight plan to PF3, click OK for "Waypoint too close" warning, click "Connect to FS" button and click "Yes" for the Live Weather option. PF3 stays running for 8 to 10 seconds or so then crashes abruptly with no warnings or advisory messages. It has been doing this since I purchased it. I have uninstalled and reinstalled PF3 and FSUIPC7 and both are in folder D:\FS Add-ons\. FSUIPC7 and PF3 are being run as administrator. FSUIPC is confirmed running in Task Manager. I have selected "Don't use skins" option. Event viewer shows faulting module as being in the dot.net frame so I ran a few file and system checks which all came up negative...ie no faults. (CHKDSK, sfc Scannow and DISM). I'm normally able to get around these issues ( FS user for over 20 years), but this has me stymied. I'm attaching the relevant files and a copy of Event Viewer read-out below. Any ideas?
