Hi @Hamza,
Your node version falls outside the supported versions. SuiteCRM 8.0 makes use of Angular 12.1.x and therefore requires node version 12.14.x, 14.15.x or a later minor version (We’ve fully tested with version 14, we’d recommend that one if possible!). Your issues should cease if you lower your version to match. The compatibility matrix will soon be updated to reflex this more accurately
and can be viewed from here.
Please let me know if this resolved your issues
