Export to PDF or XLSX

After migration from CRM 2011 to CRM 365 ON-PREMISE, there is a problem with standard export of reports in any format (pdf, xlsx, ttif, html).
Sometimes (very rarely) there are no problems, but most often the CPM immediately gives an export error "An error has occurred. Please try again later."
Also there is no way to print. After clicking on the printer icon, CPM offers to print not "to a printer", but in pdf. If allowed, the above error occurs.
The problem with printing is not critical, but the impossibility of exporting to pdf or xlsx greatly interferes with work
Tell me what you need to enable to export without problems?
Thank you!
