Only started doing this with the new updated version. If possible, can I get an older version of Fsuipc??
My system is as follows; Log Name: Application DESKTOP-N8JMRCU
AMD Ryzen 7 9800X3D 8-Core Processor (4.70 GHz)
32.0 GB (31.2 GB usable)
NVIDIA GeForce RTX 3080 Ti (12 GB)
AMD Radeon(TM) Graphics (486 MB)
2.92 TB of 4.57 TB used
64-bit operating system, x64-based processor
Windows 11 Pro
Thanks Robert
That is an MSFS ctd, and nothing to do with FSUIPC7. FSUIPC7 is an external app ans in no way should cause MSFS to CTD. And even if it somehow did, this would be due to SimConnect and would also be an issue for Asobo.
I am currently away/travelling and do not have access to any older versions. You may find this in some other posts, but this won't help, but you are welcome totry.
There is an issue where FSUIPC7 can crash, if you have an axis assignment to an input event, and there is a beta version of FSUIPC7 that fixes this issue.
I see you have created a 2nd post for the same issue. I will delete this post.
Note I am currently on holiday/travelling, hence the delay in response. I will be back at work tomorrow afternoon.

Here's 7.5.8 for you to try, but I would be very surprised if this helps with this issue:
Rename your current FSUIPC7.exe so you can switch back, and download and save this version to the same folder as your current FSUIPC7.exe
Also, when does it CTD? What were you doing at the time? Can you show me / attach your FSUIPC7.log file please.
Note there is a CTD issue when using presets that try and use the F:KeyEvent function with a string id parameter. This is a bug and has already been reported to Asobo - see https://devsupport.flightsimulator.com/t/custom-simconnect-events-with-numerical-id-triggering-ctd-when-used-with-f-keyevent/18660
Is this your issue?
