Program Crashing & .NET issues

[brennanwalls]

experiencing a similar issue to #15 on win10 with a key difference and some additional info.

on first run from a fresh program install it will convert all unconverted files in my telemetry folder. after it completes the first conversion it will crash and then crashes regardless if new files exist in the folder on restart.

event viewer shows error on mu.exe faulting module daq.dll

Exception code: 0xc0000005
Fault offset: 0x0000000000024250

Faulting application start time: 0x01d9e644e9db1ae2

also getting a .net error

i am on .net 4.8.1 using Microsoft's doc to verify

downgraded to Mu version 1.9.4.0 to see if that resolved the issue. program still didn't run, but noticed i had a "repair install" option when uninstalling.

repair fails with these errors in log:

which led me to https://github.com/orgs/wixtoolset/discussions/6441 - it looks like microsoft changed the certs and rebuilt .net 4.8 and didn't change the URL. could this have anything to do with my event viewer .net error showing i'm using .net 4.0?

update: after confirming i had telemetry turned on in all cars i was testing (i didn't) it appears to be reliably converting new files and then crashing. It would be nice to have Mu running alongside iRacing to be able to save setups along with the over advertised 'live' features but being able to see the data in MoTeC is my real desired outcome. Currently racing a session -> running Mu (it crashes after convert) -> opening the converted file with MoTeC delivers desired results.

Looks like MS once again messed with .Net and the .Net Framework runtime that is causing a mess for those that try to include it in their installers.

As for Mu crashing, is Mu having trouble with a specific telemetry file?

Having the exact same problem. Mu successfully converts all telemetry files that have been run since last use, then immediately closes.

Double Edit: I deleted all the data in the telemetry folder, and after a few PC restarts, now Mu stays open as it used to. Weird.
