Hi, I'm experiencing crashes on my Wemos D1 mini when running code that uses the TaskScheduler library. I've checked the error logs, and I'm getting the following error messages related to TaskScheduler. I'd appreciate any help in troubleshooting this issue. Thank you.

I recently had a similar error which was related to two problems: when I included painlessmesh and TaskScheduler in the same file it wouldn't work so I just included painlessmesh. Another problem was using debug build in platformio which also caused my D1 mini to crash.
