Ionic Capacitor Error occurs sporadically in app with polyfills

Question

I am using Ionic 5 with Capacitor 2.4. Sometimes there are errors at runtime like this when running on android or apple devices:

"@capacitor://localhost/3.008c706ad59f318aa3fd.js:1:3212\n__tryOrUnsub@capacitor://localhost/main.c68298d83b828b6fc082.js:1:286188\nnext@capacitor://localhost/main.c68298d83b828b6fc082.js:1:285417\n_next@capacitor://localhost/main.c68298d83b828b6fc082.js:1:284580\nnext@capacitor://localhost/main.c68298d83b828b6fc082.js:1:284355\n_next@capacitor://localhost/main.c68298d83b828b6fc082.js:1:1180252\nnext@capacitor://localhost/main.c68298d83b828b6fc082.js:1:284355\n_next@capacitor://localhost/main.c68298d83b828b6fc082.js:1:1180252\nnext@capacitor://localhost/main.c68298d83b828b6fc082.js:1:284355\ndispatch@capacitor://localhost/main.c68298d83b828b6fc082.js:1:1266164\n@capacitor://localhost/main.c68298d83b828b6fc082.js:1:1311804\nonInvoke@capacitor://localhost/main.c68298d83b828b6fc082.js:1:1088017\nrunGuarded@capacitor://localhost/polyfills.4ea97ed0da6445bc9427.js:1:2235\n@capacitor://localhost/main.c68298d83b828b6fc082.js:1:1311791\n_execute@capacitor://localhost/main.c68298d83b828b6fc082.js:1:44143\nexecute@capacitor://localhost/main.c68298d83b828b6fc082.js:1:43992\nflush@capacitor://localhost/main.c68298d83b828b6fc082.js:1:707896\nflush@[native code]\nrunTask@capacitor://localhost/polyfills.4ea97ed0da6445bc9427.js:1:2731\ninvokeTask@capacitor://localhost/polyfills.4ea97ed0da6445bc9427.js:1:8369\n@capacitor://localhost/polyfills.4ea97ed0da6445bc9427.js:1:32140"

I do not have any ideas why or when this happens. It is not reproducible and occurs sporadically with some users of my app.

Any ideas?

Thanks, Maik.
