Describe the bug / error

I have built an SPFx package containing 1 form webpart and deployed it into Sharepoint A (site collection app catalog) and Sharepoint B (global app catalog):

• Sharepoint A - web part is fully working (desktop/mobile emulation/mobile)
• Sharepoint B - when browsing on desktop it works fine, but as soon as I switch to mobile emulation/mobile I get this on-screen error:

ERROR:

and also this Console error:

as soon as I cancel emulation and do refresh, the error is gone.

I have also tried with SPFx 1.18.2 and 1.12.1 but happens all the time. Could there be any problem with Sharepoint settings? Catalog?

Thanks

Steps to reproduce

1. Deployed SPFx package and added it into site
2. Added webpart into sitepage
3. Webpart throws error in mobule emulation

Expected behavior

I expect Sharepoint to render webpart in mobule emulation

UPDATE - We have tested the solution on multiple browsers on Android and the only one that works is Firefox - Edge/Chrome/Opera crash.
