    • PC: Windows 10, 32GB RAM, Intel(R) i7 6 Cores @ 2.60GHz, NVIDIA RTX 2070 w/ 8GB VRAM (Unreal Engine on C:/ drive, project on external E:/ drive [This is necessary for storage constraints])

Hello,

I am encountering a large number of issues when running Lyra Visual Studio (Debug). These issues only occur when the project is run through Visual Studio. The vast majority of issues (and what I am focused on) are asset loading issues. The steps taken to cause the issues are as follows:

  1. Open Lyra project, configured with EOS (OSSv2), in Visual Studio 2022
  2. Select project as Startup Project
  3. Press F5 key to run project in Debug mode
  4. Select yes when prompted to rebuild (build succeeds)
  5. Run Lyra project, select Play Lyra, Start a Game, and Elimination with Bots Enabled and Network set to Online

Afterward, I encounter many lines of the following warnings:

(You may have changed the type after the connections were made)

And many more similar issues. These eventually lead to a breakpoint. Once the breakpoint is hit, I can tell VS to continue, and successfully run Lyra with no visible issues (other than slowish load times, likely stemming from the earlier deletion of the DDC folder).

I have ensured the project has run properly in the Editor, which it does. It gives me many warnings, and even a few errors, but no detrimental impact is made other than the time it takes to wait for everything to load twice. I would GREATLY appreciate it if anyone could provide some ideas as to how to fix this.
