Issue is that your /data/data/com.termux directory is owned by uid 10600, the same as termux app process security context c88,c258 but security context assigned to the directory is c81,c258, which is for uid 10593, resulting in selinux denials.
- Did you install termux previously and uninstalled it?
- Are you rooted?
- Did you restore termux app data with a backup app?
If you are rooted, there may have been root owned files under /data/data/com.termux that prevented deletion of the directory during last uninstallation.
If you are rooted, then run su -c "rm -rf '/data/data/com.termux'" from a failsafe session, then uninstall termux app and install termux app again.

If you are not rooted, then try uninstalling termux app, then rebooting and installing it again. If same issue, then factory reset would likely be required since won't be able to delete directory or restore its context with restorecon without root AFAIK, the adb shell user doesn't have such privileges either.
I checked the connection to http://termux.net/bootstrap/ and i get PAGE_NOT_FOUND.
That is from very old version. Termux does not download bootstrap anymore and is irrelevant.
Closing since not an issue with termux app itself.
Multi-Category Security
The c[0-9]+,c[0-9]+,c[0-9]+,c[0-9]+ categories are part of Multi-Category Security (MCS) and required to Isolate the app data from access by another app and Isolate the app data from one physical user to another. Both the process and file security context have categories assigned and the process categories must be a superset or equal the file categories to be allowed access. For example for c160,c256,c512,c768:
- The first category
c160is forappidforuid10160and it would get changed toc161foruid10161. The second categoryc256would get incremented toc257whenappidcrosses255and first category would get reset toc0and same will happen whenappidcrosses511. - The third category
c512is foruserid0(primary user) and it would get changed toc522foruserid10(secondary user). The forth categoryc768would get incremented toc769whenuseridcrosses255and third category would get reset toc0and same will happen whenuseridcrosses511. - A process context with security context
c160,c256,c512,c768will be able to access files with categoriesc160,c256,c512,c768or files with no categories but not with categoriesc161,c256,c512,c768(differentappid) orc160,c256,c522,c768(differentuserid). - The
uidfor normal apps withAID_APP_START >= uid < AID_SDK_SANDBOX_PROCESS_STARTis converted toappidwith((uid % AID_USER_OFFSET) - AID_APP_START). - The
uidis assigned to apps with(userid * AID_USER_OFFSET + AID_APP_START + appid).
