android emulator on windows10 crashing when runninng app

just looking for info more than a solution i think

i bought a course in android app development and am slowly going though it. also doing a introduction course to Java to begin to understand the concepts and structure required to code.

in one of the modules, i am getting the following code error which seems to be crashing the app. The error code seems to be from the emulator part of the build.

logcat is not indicating debug issues and build says ok and not highlighting errors from the app build section.

but then what do I know if you are starting

i have run other apps we have built and they run ok on the emulator so for some reason its just this module download which is crashing it. but i could really begin to understand the coding of this module if I had an app that worked,

thanks
