Face weird issue - sometime stuck at logo and sometime not

Facing strange issue after changing the theme. At one moment it is average and at other moments struck at loading the logo
chrome developer tool shows this error

I already tried bench build and update --reset commands

I have the same issue, here’s my experince linked, you are not alone lol

Is there any minification processes happening, such as Cloudflare’s auto minify feature or a proxy that removes sourceMappingUrl values from the end of the JS bundle files?
