Unable to upload CSV file crypto

When I try to upload any csv file- even the sample universal template provide by Turbo TAX, it is only goes in circles and upload is not completed. Eventually it times out. It does not give me an error. I have tried my csv file as well and having this issue since 10 days. I am aware of the format and uploaded the file last year for 2022 taxes successfully. But this year, Turbo tax will not upload any file. This is an issue with the system and needs to be fixed asap.

I ma not sure how to resolve this issue and need help. Customer support saying the same thing- clear cache, restart laptop, etc. tried multiple browsers as well. Please provide actual solution. to the problem.
